An Evangelistic Approach to Children of the Brantford Seventh-day Adventist Church in Brantford, Canada
Authors:   ,   Andrews University, Gietsel Alexander
Published: June 2023

Problem Over the past five years (2015-2020) the Brantford Seventh-day Adventist Church has experienced a decline of baptism among young people ages 10-14. Some of them have been involved in church programs, and some have attended the local Christian school. According to Barna (2003a), children are more ready to accept Jesus at ages 10-14. At Brantford Seventh-day Adventist Church, this is the average range of the children. This church has more than 80 families and more than twenty-five children at that age group. After many of them leave for high school, they lose interest in baptism and in following Jesus. Method With the help of my adviser and church leaders, a six-week seminar was conducted to address the situation. The seminars were intended to provide a biblical view on parenting and to educate the parents on how to guide their children to accept Jesus. These seminars were held in the local church on Sabbath afternoons. Parents were asked to fill out questionnaires before and after the seminars. This provided an understanding of the relationships that parents have to the unbaptized youth, age 10-16. Results Due to the COVID-19 pandemic, the seminars were not so well attended but the six parents who attended gained valuable information. Parents shared their experiences and their practices of raising their children and understood more clearly their responsibility, God’s call for them, and an improved biblical foundation of parenting. The parents of Brantford church, who participated in this study understood that the church is a place of spiritual guidance, and so is the school, but the home is the primary place where the children receive spiritual nurture, guidance, and leadership for their spiritual lives. They were convinced that family worship, church attendance, and quality time with their children, were crucial to their gradual conversion and decision for baptism. Conclusion All of the parents who attended the seminar completely agreed with the content of the presentations and were willing to implement them in their families, and the leaders were fully supportive. The concern I had before the seminars that parents would not accept the content very willingly seemed to have vanished during the seminars. Most importantly they were equipped with the materials that they needed for raising their children. These seminars can be modified and used to further nurture the congregation, and as outreach in the community.
Missional Leaders' Multiplication Through Holistic Discipleship: The Fishermen Project as a Model for German Millennials in the Central Rhenish Conference
Authors:   ,   Andrews University, Badorrek Christian
Published: June 2023

Problem If not through the influx of Seventh-day Adventists from diverse countries and their missionary efforts, the membership of the Seventh-day Adventist Church in Germany would be stagnant. Most growing churches consist of people with migrant background and a large number of them conserve their native languages in their activities. Consequently, new approaches to reach the extremely secular indigenous population are rare, since the number of people who naturally have the potential to connect with them is rapidly declining. This downward spiral leads to an overaged Seventh-day Adventist church in Germany and seems to accelerate. Only very few millennials are active and committed in building and growing the church. The purpose of this dissertation is to develop, implement, and evaluate a holistic discipleship model for millennials in order to foster new leaders who will reproduce and multiply a missional lifestyle within their generation. Method This study aims at indigenous German-speaking male millennials affiliated to the Seventh-day Adventist church within the 18-30 age range. Through personal interviews and surveys, the participants' spiritual transformation is measured, in order to evaluate the effectiveness of the designed process. Results Due to the small number of participants of the project, the collected quantitative data is not statistically valid. Yet, the qualitative data gives evidence that the developed holistic discipleship program had a positive spiritual impact on the millennials involved. Whereas the goal of multiplying leadership seems to require more time, other positive effects became visible in the lives of the participants, like a deepened relationship with God, a more intimate connection to other believers, and the motivation to witness about one's faith. Conclusions A holistic approach to discipleship, using a small group and a prolonged time-period, while establishing a close personal relationship between the leader and the participants, is not only biblical but also effective in promoting discipleship and spiritual growth within the millennial generation.
Training Local Church Leaders To Study and Teach the Bible Inductively at Manteca Seventh-day Adventist Church
Authors:   ,   Andrews University, Blum Bruce
Published: June 2023

Problem Seventh-day Adventist churches in Northern California are experiencing a trend toward larger districts and fewer pastors per capita. A decreasing pastoral presence means that local churches are more dependent on volunteers to lead out in the spiritual care and feeding of the church family. In this setting, much depends on the competence of volunteers who teach the Bible. Most of these volunteers have not had the benefit of formal training in hermeneutics, biblical languages, or effective teaching methods, yet they are called on to facilitate Scripture study that leads to inspiration, engagement, and transformation. Method I proposed in this project that training in inductive Bible study skills is an accessible way of multiplying and strengthening volunteer teachers in a local church setting. This project was informed by: (a) insights from the Bible itself on healthy engagement with Scripture; (b) a review of the literature on inductive Bible study, guided inductive teaching, and related teacher-training methods; (c) my own previous experience receiving training and training others. With this foundation, I planned a training experience and offered it at the Manteca Seventh-day Adventist Church. The training consisted of about 20 hours of experiential learning. I taught participants skills, and then they immediately used these skills in guided practice, receiving group feedback to get the maximum amount of learning in a short period of time. Because participants were using what they were learning during the course sessions, I was able to observe their skill development as it happened. I also asked them to fill out a before and after survey that had them give a self-assessment of their development in several skill areas covered in the training experience. Results Participants showed significant growth in the skills we worked on in the sessions, both measured observationally and as reported in their self-assessments. High levels of engagement as well as a sense of worship and appreciation of God and Scripture were also apparent among the participants, even though the sessions were largely focused on skill building. It has been more difficult to assess how effectively the participants have transferred their new skills to their teaching ministry after the training. Conclusions In a relatively short period of time, through an intensive, experiential training course, volunteer teachers can improve significantly in their ability to: (a) grasp Scripture for themselves, (b) use questions to encourage others to make their own discoveries, (c) facilitate application of those discoveries to life.
Creating a Culture Shift in the Tracy Seventh-day Adventist Church To Attract Millennials and Generation Z
Authors:   ,   Andrews University, Kraft Tyler
Published: June 2023

Problem The Tracy Seventh-day Adventist Church is facing a shortage of committed leaders and volunteers. Most of the current ones have been serving for several decades and they desire to train and mentor potential replacements, but there are not enough people from the younger generations to take up the mantle. The demographics of the church do not represent the demographics of the community; older adults are overrepresented and younger adults are underrepresented. The church needs more youth and young adults to relieve the older members, or else the church's existence could be in jeopardy. Method In consultation with my advisor and using information gleaned from theological reflection and a review of relevant literature, I developed a three-phase intervention that had a total of 13 steps. The first phase included six steps: strengthening the church's prayer ministry, deepening relationships with core influencers, recalibrating the church's mission and vision, taking church leaders through the Growing Young assessment, familiarizing the church body with Growing Young concepts, and finally having the church members take the initial Growing Young assessment. The second phase consisted of five steps: creating a Growing Young team, developing and launching an introductory membership class, providing individualized coaching, preaching intentional sermon series, and starting a young adult ministry. The third phase included two steps: having the church members take the final Growing Young assessment, and processing the outcome and determining the next steps. Results The data from the assessments showed incremental improvements (between 1.3% and 6.5%) in five of the six Growing Young indicators and a small decline (0.9%) in the sixth. The changes were not substantial enough to be of much significance, but they do seem to suggest a positive trend was occurring. The final assessment indicated that the church members continued to engage in their strengths throughout this process while they worked to improve their weaknesses. Conclusion The COVID-19 pandemic caused several issues with this intervention, and despite my best efforts to adapt, the results were hampered by the problematic circumstances. I believe the methodology was sound and would have produced greater results had there not been a pandemic. Yet despite COVID-19, there were indicators that the church was heading in the right direction, and I would not hesitate to implement this project again. More than that, the impact that this project made on me was invaluable in terms of the personal, academic, and spiritual growth I experienced.
Finding a Voice: A Preaching Model To Address the Postmodern and Post-Soviet Young Adults at the Compass Seventh-day Adventist Church in Tallinn, Estonia
Authors:   ,   Andrews University, Cederstrom Mervi
Published: June 2023

Problem In Northern and Eastern Europe, probably more than in any other part of the world, the gap between the inner culture of the Seventh-day Adventist Church and that of the surrounding culture has grown large, hindering the church’s ability to share the Gospel to young adults (ages 16-29) in a meaningful and clear way. It is especially true about people who have grown up in the Postmodern and Post-Soviet context of Estonia and have very little biblical knowledge. This present study concentrates on homiletics and how this culture gap can be bridged via preaching. Method A five-part preaching series was created with young adults in Estonia being the primary target audience. The sermons were preached in Compass Seventh-day Adventist Church in Tallinn, Estonia from November 20 until December 18, 2021. All listeners were invited to fill in a feedback form after each church service. Over the period of five weeks, 116 evaluation forms were collected and the anonymous feedback analysed. Results The church members and visiting guests were given an opportunity to evaluate my sermons and express their ideas on different preaching-related topics. The main areas of feedback were as follows: topic and organisation of the sermon, the role of the preacher, inclusiveness, and narratives. Every thematic section had both open-ended questions and questions with scales from 1 to 5. The results showed that young adults―both the regular attendees and occasional guests―are interested in topics that touch their everyday reality and choices, they appreciate preacher's openness and emotional honesty, they find it easiest to follow sermons with a simple structure and a single focus, their attention is caught by good stories, they appreciate supportive visual materials, and they long for an inclusive Christian community where they could be seen and appreciated as individuals. Conclusions Preaching in a Postmodern and Post-Soviet context where the general knowledge of Christianity and the Bible are very low is a constant challenge. Yet, with a careful sermon preparation process which takes into account the individualistic and fragmented worldview of the Postmodern people, it is possible to preach sermons that touch both the hearts and minds of young adults. When the context-sensitivity is supported by the preacher's emotions and integrity of life, the preaching act can be and is an effective way of communicating the Gospel truths.
An Inquiry Into the Time Elements of the Fifth and Sixth Trumpets of Revelation Nine
Authors:   ,   Andrews University, Mole Robert
Published: June 2023

Statement of the problem It was the purpose of this investigation, (l) to discover whether the dates as given in the Litch-Smith view of Revelation the ninth chapter, which ends the times of the fifth and sixth trumpets on August 11, 1840, agree with both the Bible and history; and if not, (2) to determine whether a solution is possible that would agree with both factors in view of the criticism presently leveled at the Litch-Smith view. This criticism is based on the seeming inability to find historical facts to support this view, and also on the exegesis of the prophetic language used. Thus this study is "An Inquiry Into the Time Elements of the Fifth and Sixth Trumpets of Revelation Nine." Importance of the study to Seventh-day Adventist Of the twenty-two beliefs of Seventh-day Adventists listed in the denominational yearbook, eleven are directly concerned with prophecy or the prophetic office. A denomination that gives such prominence In its teachings to prophetic exposition should be sure that history agrees with Biblical events, prior to attesting to classify them as fulfilled prophecy. This is especially true because of the challenge presented by many Bible scholars to faith in prophecy. However, the problem under consideration is not one of the major or fundamental beliefs of the church. Because of the difficulties encountered in seeking to fit the events as pictured by Litch and Smith with both the Bible and history, it is suggested that there must be a missing factor involved, or one erroneously interpreted. Hence this investigation was made. Present status of the problem The problem of Revelation nine has been in recent times practically untouched. Secular historians in general ignore prophecy as having nothing to do with their work, and many Bible scholars sought only to prove a preconceived idea, in that the symbolism of the Bible has not been understood. There is a language problem in this prophecy that also helps make it difficult to clarify. Mary churches of the present day do not stress the importance of prophecy. Hence it is almost completely ignored. After the seeming fulfillment of Litch's prediction in August, 1840, when it seemed to many that Turkey surrendered her independence to the European powers, few troubled themselves to study the matter further. In general, the followers of the Litch-Smith view accepted the presentation as accurate. This is especially true in view of the statements concerning this event by Mrs. E. G. White in The Great Controversy Between Christ and Satan. However, as more is now becoming known of the Middle East, grave doubts have arisen as to the accuracy of this prediction. Yet while many have worked on this problem, they have either failed to reach a concurring conclusion, or else have refrained from presenting their findings.

Published: June 2023

Objective. The objective of the article is to determine the essence of marketing management of a tourist enterprise in the context of the paradigm of sustainable development, to justify the peculiarities of the operation of tourist enterprises based on the active introduction of management of the enterprise's marketing activities.

Methods. The theoretical and methodological basis of the research is the position of modern economic theory, management theory, scientific works of domestic and foreign scientists in the field of marketing management. The methods that ensure its logical essence are used in the research - the dialectical method of scientific knowledge, the method of system-structural analysis, the method of modeling complex systems.

Results. In the article, the authors consider the issue of marketing approaches to managing the activities of a tourist enterprise in the context of the paradigm of sustainable development. It was determined that the management system should have a marketing orientation, which will stimulate the development of strategies for the transition of enterprises from outdated forms and methods of management and management to new, scientifically based market methods that involve a marketing approach. It was determined that the development of a new system of complex management of marketing activities is relevant, which should determine the mission of the enterprise, what resources and in what period will be needed by the tourist enterprise to achieve marketing goals; how to achieve the most effective use of the resources involved. The authors note that the marketing management of a tourist enterprise requires the planning of marketing activities, which should have a comprehensive nature and be implemented at the corporate, local and structural unit level. The structural-functional model of marketing management of a tourist enterprise developed by the authors in the conditions of the paradigm of sustainable development gives an idea of a system object, which allows you to identify the regularities of the object's functioning and trace the cause-and-effect relationships between the behavior of the system and the nature of the influence that is carried out.

Published: June 2023

Objective. The objective of the article is to research modern approaches to the effectiveness of public authorities and the peculiarities of their economic assessment at the local level.

Methods. The methods of theoretical search, analysis and synthesis, systematization and generalization, scientific abstraction, tabular method, and statistical research methods (for determining economic efficiency indicators) were used in the performance of this scientific research.

Results. Based on the theoretical generalization of the approaches of Ukrainian scientists regarding the definition of the categories "management efficiency", "effectiveness" and "efficiency" in relation to the activities of public authorities (accepted for the state and municipal level as a single interpretation), it is determined that it is managerial, social, economic and political a category determined by the influence of the subject of management on the object of management with the aim of achieving the set goal (result), in which the object of management moves to a new state with the optimal use of resources needed to support such a transition. As a methodological basis, the work implements a mixed approach to evaluation, which is a compilation of the composite approach (which aims to determine the degree of influence of managerial work on the performance of the government body as a whole) and the multiple approach (which is an attempt to evaluate efficiency using generalizing indicators). With its use, an assessment of the economic efficiency of the municipal authorities of the city of Kryvyi Rih was carried out. By means of the analysis of indicators of resource strategic efficiency and general indicators of economic efficiency of public authorities (municipal authorities) of the city of Kryvyi Rih in 2019-2021, a high level of efficiency was ascertained, which ensures the return of all available resources of the territorial community and meets the goals of regional development and strategic interests of the state.

This study aims to analyze the relationship and influence of academic motivation and perceived creativity fostering teacher behavior (P-CFTB) on student engagement in Statistics online learning courses in Indonesia. The research used a cross-sectional design study with a quantitative approach. Three standardized scales (academic motivation scale, perceived creativity fostering teacher index, and university student engagement inventory) were filled out by 533 psychology undergraduates who participated. All data were analyzed statistically by descriptive, correlational, and multiple linear regression tests. The results show that academic motivation and student engagement, P-CFTB and student engagement were related moderately and positively (r = 0.582, r = 0.593; p < .001, respectively). Furthermore, academic motivation and P-CFTB simultaneously affected students’ learning engagement by 48%. The result shows that when students’ academic motivation is combined with creativity fostering teacher behavior, student engagement in online learning increases.

The research uses descriptive method. Data collection technique used observations of students with special needs to see the difficulties in understanding mathematical concepts (dyscalculia), and interviews conducted with mathematics teachers to complement the results of the observations. The research sample is deaf students, blind students, and mentally retarded students in the Jember district. The data analysis technique in this study uses the flow model. The results of this study were that the level of achievement with good assessment categories was dominated by blind students, namely from 10 aspects of the assessment only weak in the section on grouping the shape dimensions, while the deaf achieved good assessments, namely 1) sorting objects based on the length and short size, 2) understanding the number of objects, 3) understanding numbers, and 4) writing and saying numbers. Meanwhile, mentally retarded students only have 1 good assessment aspect, namely understanding the length of objects. The conclusion is that dyscalculia is mostly suffered by mentally retarded children, deaf children suffered moderate level, and the best level of the subject is blind children.

To evaluate research some bioactive properties of the extract of the Crocus cancellatus subsp. mazziaricus (Herb.) B. Mathew, 1982 the antioxidant activities of these extracts were analyzed by means of cleaning methods (DPPH, ABTS scavenging activity), β-carotene/linoleic acid test system and FRAP activity. Phenolics and flavonoid contents as the equivalents of gallic acid, quercetin respectively. The phenolic content of the extracts was analyzed using HPLC. Brine shrimp lethality test was applied to analyze cytotoxic activity. The obtained results indicated that the highest phenolic compound ferulic acid with 2376.2±0.00 µg/g was in extracts. The highest total phenolic and flavonoid were found in the ethanolic extracts. The aerial part-methanol extract exhibited the highest antioxidant capacity and the corm acetone extract the highest amount of ferric reducing power activity. Among the four different extracts, the acetone extract showed the highest amount of radical scavenging both corm and aerial parts. The brine shrimp lethality assay of bulb ethanol extract has showed good cytotoxic with LC50 of 320.535 μg/mL. This study will be a source for future studies.
Invariant forms and control dimensional parameters in complexity quantification
Authors: Abarzhi Snezhana I.
Published: June 2023

Non-equilibrium dynamics is omnipresent in nature and technology and can exhibit symmetries and order. In idealistic systems this universality is well-captured by traditional models of dynamical systems. Realistic processes are often more complex. This work considers two paradigmatic complexities—canonical Kolmogorov turbulence and interfacial Rayleigh-Taylor mixing. We employ symmetries and invariant forms to assess very different properties and characteristics of these processes. We inter-link, for the first time, to our knowledge, the scaling laws and spectral shapes of Kolmogorov turbulence and Rayleigh-Taylor mixing. We reveal the decisive role of the control dimensional parameters in their respective dynamics. We find that the invariant forms and the control parameters provide the key insights into the attributes of the non-equilibrium dynamics, thus expanding the range of applicability of dynamical systems well-beyond traditional frameworks.

Published: June 2023

By 2050, around 70% of people will live in urban areas. According to the 11.2 target of UN SDG “Sustainable cities and communities” to provide access to safe, affordable, accessible, and sustainable transport systems for all, the aim of the paper presented was to investigate accessibility and connectivity of urban territories by public transport systems. The main emphasis of the research was directed at transport infrastructure, which can be seen as sustainable, including public transport. The quality of life in a large city is determined by the ability to get from one destination to another quickly and efficiently. To implement this task a methodology has been developed to assess the connectivity and accessibility of urban areas. The method, based on an intermodal transport graph, is presented as an example of assessing accessibility and connectivity in different districts of Saint Petersburg (Russia), Helsinki (Finland), Stockholm (Sweden), and Amsterdam (Netherlands). The results are presented as graphs with clusters of city blocks presented as points. It is indicated that different areas of the city are connected through time values differently. The method can be used to make urban planning decisions about the provision of urban infrastructure, allows for ongoing monitoring of the situation, and filling in the gaps.
Nuclear shapes are geometrically determined by the excess surface area of the nuclear lamina
Authors: Dickinson Richard B. , Lele Tanmay P.
Published: June 2023

Introduction: Nuclei have characteristic shapes dependent on cell type, which are critical for proper cell function, and nuclei lose their distinct shapes in multiple diseases including cancer, laminopathies, and progeria. Nuclear shapes result from deformations of the sub-nuclear components—nuclear lamina and chromatin. How these structures respond to cytoskeletal forces to form the nuclear shape remains unresolved. Although the mechanisms regulating nuclear shape in human tissues are not fully understood, it is known that different nuclear shapes arise from cumulative nuclear deformations post-mitosis, ranging from the rounded morphologies that develop immediately after mitosis to the various nuclear shapes that roughly correspond to cell shape (e.g., elongated nuclei in elongated cells, flat nuclei in flat cells).

Methods: We formulated a mathematical model to predict nuclear shapes of cells in various contexts under the geometric constraints of fixed cell volume, nuclear volume and lamina surface area. Nuclear shapes were predicted and compared to experiments for cells in various geometries, including isolated on a flat surface, on patterned rectangles and lines, within a monolayer, isolated in a well, or when the nucleus is impinging against a slender obstacle.

Results and Discussion: The close agreement between predicted and experimental shapes demonstrates a simple geometric principle of nuclear shaping: the excess surface area of the nuclear lamina (relative to that of a sphere of the same volume) permits a wide range of highly deformed nuclear shapes under the constraints of constant surface area and constant volume. When the lamina is smooth (tensed), the nuclear shape can be predicted entirely from these geometric constraints alone for a given cell shape. This principle explains why flattened nuclear shapes in fully spread cells are insensitive to the magnitude of the cytoskeletal forces. Also, the surface tension in the nuclear lamina and nuclear pressure can be estimated from the predicted cell and nuclear shapes when the cell cortical tension is known, and the predictions are consistent with measured forces. These results show that excess surface area of the nuclear lamina is the key determinant of nuclear shapes. When the lamina is smooth (tensed), the nuclear shape can be determined purely by the geometric constraints of constant (but excess) nuclear surface area, nuclear volume, and cell volume, for a given cell adhesion footprint, independent of the magnitude of the cytoskeletal forces involved.

Amomi fructus is rich in volatile components and valuable as a medicine and edible spice. However, the quality of commercially available A. fructus varies, and issues with mixed sources and adulteration by similar products are common. In addition, due to incomplete identification methods, rapid detection of the purchased A. fructus quality is still an issue. In this study, we developed qualitative and quantitative evaluation models to assess the variety and quality of A. fructus using GC, electronic tongue, and electronic nose to provide a rapid and accurate variety and quality evaluation method of A. fructus. The models performed well; the qualitative authenticity model had an accuracy of 1.00 (n = 64), the accuracy of the qualitative origin model was 0.86 (n = 44), and the quantitative model was optimal on the sensory fusion data from the electronic tongue and electronic nose combined with borneol acetate content, with R2 = 0.7944, RMSEF = 0.1050, and RMSEP = 0.1349. The electronic tongue and electronic nose combined with GC quickly and accurately evaluated the variety and quality of A. fructus, and the introduction of multi-source information fusion technology improved the model prediction accuracy. This study provides a useful tool for quality evaluation of medicine and food.

Prior research in cyber deception has investigated the effectiveness of the timing of deception on human decisions using simulation tools. However, there exists a gap in the literature on how the availability of subnets and port-hardening influence human decisions to attack a system. We tested the influence of subnets and port-hardening on human attack decisions in a simulated environment using the HackIT tool. Availability of subnets (present/absent) within a network and port-hardening (easy-to-attack/hard-to-attack) were varied across four between-subject conditions (N = 30 in each condition): with-subnet with easy-to-attack, with-subnet with hard-to-attack, without-subnet with easy-to-attack, and without-subnet with hard-to-attack. In with-subnet conditions, 40 systems were connected in a hybrid topology network with ten subnets connected linearly, and each subnet contained four connected systems. In without-subnet conditions, all 40 systems were connected in a bus topology. In hard-to-attack (easy-to-attack) conditions, the probabilities of successfully attacking real systems and honeypots were kept low (high) and high (low), respectively. In an experiment, human participants were randomly assigned to one of the four conditions to attack as many real systems as possible and steal credit card information. Results revealed a significant decrease in the proportion of real system attacks in the availability of subnetting and port hardening within the network. Also, more honeypots were attacked in with-subnet conditions than without-subnet conditions. Moreover, a significantly lower proportion of real systems were attacked in the port-hardened condition. This research highlights the implications of subnetting and port-hardening with honeypots to reduce real system attacks. These findings are relevant in developing advanced intrusion detection systems trained on hackers' behavior.

The Microwave Palaeointensity System at the University of Liverpool has developed, over 30 years, into the current third generation version; a combined 14 GHz microwave resonant cavity and superconducting quantum interference device magnetometer integrated microwave system. The use of microwave energy minimises the bulk temperatures required to demagnetise and remagnetise palaeomagnetic material, thereby limiting the significant problem of thermo-chemical alteration of magnetic minerals. Here we review the microwave palaeointensity approach, including its development, technical details, modern usage and results. We have carried out a comprehensive analysis of 20 palaeointensity studies, published between 2008 and 2022, where data collected using the microwave system may be compared with various other methods at the site level. An assessment of microwave results revealed no statistical bias compared to thermal, and known field data. We also present results from a new controlled experiment which tests the ability of the microwave to accurately recover weak, ancient palaeointensities when strongly overprinted. We conclude that the microwave system can be used for the primary method of determining accurate absolute palaeointensities or as part of a multi-method approach, and is well suited to a wide range of material from archaeomagnetic samples to ancient rocks.
Effects of CO2 injection factors on preventing spontaneous coal combustion in coal mine gobs: a simulation approach
Authors: Fan Jiafeng
Published: June 2023

The spontaneous combustion of residual coal in the gob seriously threatens the safety of coal mining. Injecting CO2 into the gob not only prevents the residual coal from spontaneous combustion but also realizes CO2 storage in the mined areas. Injection flux and burial depth of the port are crucial for CO2-preventing fire in coal mine gobs. In this study, the distribution of the oxidation zone in the Tanyaoping coal mine was field-measured, and the coal oxidation kinetic model was built by the adiabatic test. Then, a 3-D mathematical model was constructed based on the conditions of the 5011 working face by COMSOL Multiphysics. Furthermore, the coupled effects of the two factors on the distribution of the oxidation zone were investigated. Increases in both injection flux and burial depth result in a decrease in the oxidation zone volume. The reasonable ranges of the injection flux and burial depth are 540–720 m3 h-1 and 30–40 m, respectively. These results provide some guidelines on how to prevent the spontaneous combustion of residual coal in mine gobs.
