Authors: Grebneva Oksana A.
Published: June 2018

The lack of reliable information about actual characteristics and parameters is the main deterrent to the effective application of mathematical and computer-modelling methods for solving problems of optimal reconstruction, adjustment, development of operational condition, dispatching control of pipeline systems. The paper presents the original formalization of the problems of testing pipeline systems for hydraulic and thermal losses as problems of active identification, assuming optimal planning and processing of experimental results on the basis of attracting a mathematical model of steady-state thermal-hydraulic state. The proposed technique consists in a stepwise testing strategy that ensures the extraction of maximum information with a minimum risk of excessive testing, is applicable for different types of testing of pipeline systems of arbitrary structure and configuration. Theoretically, and for an illustrative example, the potential efficiency of combining thermal and hydraulic tests of pipeline systems is shown, which is manifested in minimizing the total number of experiments to obtain a given accuracy in determining the actual characteristics of pipeline systems and the predictive properties of the model.

Published: June 2018

Heat supply is socially and economically important in our country. In this regard, high-quality monitoring and planning of the development of heat supply systems are a strategic vector of scientific research. This paper is focused on the studies demonstrating how to choose a methodological approach to describe changes in heat consumption in the retrospective. The change in heat consumption is described using multiple regression models. In the first part of the paper, the parameters for the regression model are determined and a statistical analysis of the obtained model is performed. In the second part of the paper, to eliminate the multicollinearity of the regression equation, the number of dependent variables in the model is reduced. A statistical analysis of the new regression model and the exponential regression model are carried out. The heat consumption values obtained using these models are compared with the statistical data. The conclusions about the quality of the obtained regression models are made. In the third part of the article, we make a forecast of heat consumption in the medium term by using a linear regression model and an exponential model.

Published: June 2018

Open coal mining companies in Kuzbass (Western Siberia, Russia) constantly face challenges to increase the economic efficiency of mining operations, reduce coal losses and increase profitability. One of the ways to increase the efficiency of open pit mining is to improve the technology for the development of coal-bearing zones of quarry fields on complex structured inclined and steep deposits. At present, the projects for promising deposits have been completed, and a number of operating open pits conduct the development of coal-bearing zones along their entire width by horizontal layers. The excavating and loading equipment for overburden and mining operations in these zones is diverse: quarry rope shovels, hydraulic backhoes or their joint work. When they work together in the coal-bearing zone, the rope shovels extracts the interbeds, and the hydraulic backhoes extract the coal seams. However, such technical solutions are not sufficiently substantiated. The fact is that rope shovels and hydraulic backhoes have their advantages and disadvantages in operating.

The Change of the Spatial Parameters of the Destruction of the Rock mass by Borehole Charge with Low-Density Tamping
Authors: Katanov Igor
Published: June 2018

Explosive destruction of the rock formation is substantiated by several theories developed by well-known scientists. The improvement of quality of preparation of rock mass to excavation, by an excavator without an increase in the value of specific consumption of explosives is important in the present time. Traditionally, to increase the impact time of detonation products on the rock hard tamping was used. The problem is in the rational redistribution of the explosion energy due to the use of a borehole charge, and in particular, in the tamping of low-density, porous materials. The more intensive attenuation of the mass velocity of particles in the material of such tamping in comparison with the mass velocity of the rock mass particles contributes to the well channel compression and increases the impact time of detonation products on the rock mass. As a result of redistribution of energy of detonation products, the specific impulse of explosion increases. The value of the radius of the controlled crushing zone increases by more than 1.6 times. The results of industrial explosions in coal mines have confirmed the theoretical reasoning.

Published: June 2018

Safety pillars are the necessary objects for underground mining of coal seams. The having been mines; safety pillars, which include the development workings, lose their purpose. The coal reserves in these pillars are significant and can be mined. However, the pillars have fracture zones in the edges. The size of the fracture zones in the marginal parts of the pillars should be taken into account when choosing a mining system and its parameters. Coal pillar stress-strain analysis was carried out by the finite element method. The developed technique for coal pillar stress-strain analysis takes into account the post-critical strain of the coal seam edge. The reliability of the technique was verified by the experimental method. The calculated and experimental values differ insignificantly. The geomechanical condition of the nine safety pillars in A.D. Ruban mine of OJSC “SUEK-Kuzbass” was studied. The enterprise mines three low dip seams at a depth of up to 290 m. The amount of losses in fracture zones is defined for the pillars, which include slopes and entries. Fracture zones in the pillars were sized taking into account the actual structure of the seam roofs: the depth of bedding, their thickness and strength characteristics. The economic effect of mining of the safety pillars is pre-computed.

Mining: Classification and Solutions
Authors: Koščová Michaela , Hellmer Mark , Anyona Seroni , Gvozdkova Tatiana
Published: June 2018

Open mining development is the cheapest method, because it uses powerful production equipment, which allows a large amount of minerals to be excavated during a shift. Working conditions in open development are less dangerous for the health of workers, and a smaller number of supervisory personnel than in underground mining is required. In the process of open development, stripping works are first carried out, i.e. the removal of the empty rocks covering the deposit. Constantly growing requirements for energy sources, metal ores and building materials cause the need for intensive development of the mining industry. There is a rejection of significant areas for the development of minerals in an open and closed way. The causes of degradation are both the mining of minerals, as well as construction, the placement of production and consumption wastes in the natural environment. Changes in the components of the environment are observed as a result of direct or indirect influence of mining enterprises activities. This requires an analysis of the entire complex of geo-environmental problems of open mining and the identification of the most urgent ways to solve them.

The Analysis of the Stress-Strain State of the System “Equipment Complex - Support - Rock Mass” in the Bottomhole Area of the Shaft
Authors: Pankratenko Alexander , Isaev Alexander
Published: June 2018

The development of new deposits enterprises requires the construction of deep and super deep vertical shafts. The duration of their construction reaches 8 - 10 years with multi-billion capital investments. To reduce the payback period of these costs, it is necessary to develop and implement effective solutions to increase the speed of sinking operations through the wide introduction of brand-new mechanized equipment complexes. In response to the sinking in the bottomhole area of the shaft a complex, the following geotechnological system is being formed: "tunneling system - support - rock mass", the regularities of which require further study. For these purposes, an analytical method for calculating the shaft support can be used in the context of consideration of a planar contact problem at various phases of the system operation. The mutual coordination of individual phases in accordance with the classical concepts of the underground structures mechanics is possible with the help of a correction factor to the magnitude of horizontal stresses in the rock mass. In this paper we developed the algorithm which determines this coefficient, taking into account the influence of the main technological factors: the jack system pressure of the complex and the speed of sinking.

Authors: Belyakov Vladimir , Kuporova Alexsandra
Published: June 2018

The article analyzes the possible substitution of long-range coal with peat fuel in boilerhouses of Batagai settlement, the Sakha (Yakutia) Republic, and technical and ecological problems that arise. Potential in-situ resources for permafrost production of moulded solid fuel with peat are examined. The study introduces two options of peat fuel production for boilerhouses: peat milling and sod peat moulding. Experimental work on sod peat drying shows that sod peat can be cut and dried to the conditioned moisture content in northern Yakutia but it is inexpedient both technologically and ecologically. A flowsheet of sod peat hydromechanised production from lacustrine peat is presented. According to it peat mass is scarified, diluted with lake water, sucked in by a pump dredge, and then pumped through a sludge line onto the lakeside where it is dehydrated in geotubes to have moulding moisture. Dehydrated geotubes are cut and peat mass is loaded into a peat spreader which stir and shape it into cylindrical peat sods, then spread it on a drying field. Further the process follows the conventional technology of harrowing, ridging, and covering dried peat.

Authors: Samir Mourad , Alama Faruz , Buysse Paul , van Nylen Tomas , Ostanin Oleg
Published: June 2018

The main directions of mining and industrial wastes’ utilization are the production of building materials, their use in the construction industry without additional processing, and also the production of metals from metal-containing raw materials. It should be noted that current waste is preferable for the production of building materials, since they preserve the primary physical and mechanical properties and chemical composition and, moreover, can reach the consumer bypassing all other steps that are mandatory for waste consolidated (transportation, storage, etc.). For the production of building materials, not less than 30% of overburden and refinement tailings are suitable, almost all metallurgical and fuel slags, waste products of fertilizers and building materials. Even larger amounts of waste can be used for various laying and burial works (construction of road bases and dams, filling of worked out areas, leveling of the relief).
Mining Waste in the Circular Economy – Idea Versus Reality
Authors: Kotarska Izabela , Mizera Barbara , Stefanek Paweł
Published: June 2018

This article constitutes an analysis of the feasibility of the application of the so popular presently idea of the circular economy in the area of mining waste management. It describes the specificity of the mining waste generated during the mining and the enrichment of copper ore, i.e. waste rock (gangue), tailings. That specificity results first of all from the character of the processes where the waste are generated and the amount of them. The waste properties are described, the implemented methods of handling it are presented, as well as the prospective technologies of recovery developed in the range of research works. The presented examples show that the implemented methods of waste rock recovery can be an illustration and model of the functioning of the circular economy (or in other words for this case wasteless economy). However, as it comes to the flotation tailings the fact has been emphasised that the research studies are being carried out for decades aimed to search a possibility to recover as much waste as possible. Those deliberations lead to the conclusion that at present in reality the only method of that waste management is to deposit it in an environmentally safe way.

The state of the issue of the underground space development rate in Russia is considered. An analysis of shortcomings of the existing tunneling equipment (tunneling shields and machines) is carried out. It is noted that a promising way of mine tunneling is screw drilling technology, the basic functional element of which is the geokhod. It is claimed that one of the key systems of the geokhod, which determines its efficiency, is transmission. It is noted that the hydraulic cylinder type transmissions implemented in practice at the present time in the form of the development prototype have both their advantages and disadvantages. This does not allow considering the hydraulic cylinder type transmission the optimal solution for its use when designing new-generation geokhod. An overview of various gearing types is made and conclusions about the prospects of using them in the geokhod transmission are drawn. It is claimed that the eccentric cycloidal gearing, according to a set of indicators, is the most suitable for its application in the geokhod transmission. Therefore, studies aimed at proving parameters of the eccentric cycloidal gearing geokhod transmission are relevant.

Published: June 2018

Technologies of surface plastic deformation (SPD) provide a hardening effect and create compressive residual stresses in the surface layer of mining machine parts. This leads to a significant increase in the limit of endurance and fatigue cyclic life, increases the life in fretting conditions, improves the quality of assembly joints fit, etc. Very complex are both the physical nature of the occurrence and the estimation of residual stresses, since the machining processes are related to complex nonmonotonic types of loading. The study shows the relevance of the development of computational methods for determining residual stresses in the processes of hardening treatment of critical surfaces of mining machine parts. At the same time, the design and development of experimental nondestructive express methods based on the determination of various physical parameters (acoustic, magnetic noise, coercive force, etc.) are relevant and promising. A model of the process is developed and numerical calculations of the residual stresses arising during the SPD treatment are carried out. The results of the calculations are in good agreement with the experimental data.

Proceeding from the general ideology of the sustainable development concept, the issues of determining the long-term social and environmental consequences of modern economic development are fundamental, and the success of implementing the ideas of economic modernization and energy efficiency depends on the active position of state and regional authorities. To move to the path of sustainable development, carefully coordinated actions in all spheres of the economy are needed. It requires a model of an organizational and economic mechanism that would ensure the transition to a "green economy", the reorientation of economic, environmental and social institutions to priority areas. Clearly, at the moment, there is an urgent need for moving to an economic model that will improve human well-being, while preserving resources and not exposing future generations to significant environmental risks. To conduct an effective environmental policy and to assess the overall effectiveness of “green” growth, it is proposed to develop a model for ensuring a transition to a "green economy", which will allow understanding the level and coordination of activities, the scale and boundaries of their impact, and most comprehensively process information on possible projected risks and possible negative effects (pollution, degradation of ecosystems).

Published: June 2018

Developing a modern view of social and environmental responsibility as a part of environmental policy and taking into account the specifics of coal industry, the article describes the obstacles on the way to its implementation in practice, the main reason of which is the weakness of ecologically oriented thinking. The study shows that Russian enterprises of the coal industry, despite their importance for the economy, are still not fully aware of the need to take into account the factors of their own impact on the environment. The environmental peculiarities of the coal industry enterprises of are determined. The styles of thinking of the management of coal companies during Soviet times and at the end of the twentieth century are traced, when Western standards of mineral resource extracting have not completely adopted yet. Ecological-and-social responsibility is understood by the authors as the highest level of environmental obligation to solve the primary ecological problems. In conclusion, the directions of implementing environmental initiatives are noted.

Research carried out at the expense of the grant RFBR No 17-02-00416-OGN is devoted to the consideration of problems of formation of a qualitatively new model of monitoring, identification and forecasting of any forms of threats and risks in the field of security of coal mining facilities. Research take into account their new aspects (cross-border network structures, lack of a single control center, presence of a large number of quasi-autonomous organizational and technical elements with their own management trajectories and localized interests etc.). Monitoring and modelling these processes is the basis of the systemic strategies of prevention of emergencies. Developing specific measures for information assurance organizational process in implementation of management action is based on the convergence of information, telecommunication and computing services to government agencies as a control object with a significant number of deviant implemented operational variables with the absence or delay of information signals about their dynamics and ensuring interdepartmental cooperation.
Lingua-Didactic Aspects of Teaching Mining Vocabulary to Mining Engineers

The current paper features the problem of teaching foreignlanguage mining vocabulary to would-be translators / interpreters and mining students. The one-industry city environment poses a challenge in front of those higher education institutions that offer a master degree in translation: as long as the best jobs in the region are offered by coal-mining enterprises, developing language and translation skills is not enough. A professional translator in a coal-mining region has to be familiar with mining vocabulary, which, like in any other high-tech production sphere, seems either too abstract or too specific for an outsider. Bachelors in coal mining, on the other hand, demonstrate a lack of communication skills if they wish to get a master degree in translation. The article states Content and Language Integrated Learning method (CLIL) as a possible solution for the problem. The method allows the instructor to employ various authentic media sources within the mining works to build up topic cases for communication skills development at the initial stage as well as to extract terminology to compile thematic glossaries at a later stage of translation skills acquisition. The paper includes some examples of CLIL application in teaching translation for coal-mining industry purposes.
Qualification of Labour Safety Criminal Violations at Russian Coal Mining Enterprises

Published: June 2018

In this paper, the issues of qualification of criminal safety violations at coal mining enterprises are discussed in detail. Firstly, a number of articles of the Criminal Code of the Russian Federation for qualification of these acts are defined. The differences between articles 143 and 216 of the Criminal Code of the Russian Federation with the analysis of a concrete example from judicial practice are considered. A similar procedure is carried out in the course of qualifying safety violations at coal mining enterprises under article 217 of the Criminal Code. In this work, the authors do not try to justify the need to decriminalize any articles of the Criminal Code of the Russian Federation, but try to work with the existing legislative framework so that the qualification rules formulated in the work can be used in practice. Also the authors formulate rules for the qualifications of the violations considered in this paper and propose amendments to the Criminal Code that do not require any “revolutionary” changes. A special difficulty is that there are no scientific recommendations on the qualification of criminal safety violations at coal mining enterprises.
Innovative Activity as a Factor of Mining Region Sustainable Development

Published: June 2018

The article considers innovative processes and innovative activity of subjects as a factor of sustainable development. Factors putting back and facilitating the innovative processes in the low-tech sector of the economy are singled out. It is substantiated that the transition to an innovative economy raises the requirements for the workforce quality, and, consequently, the organization of labor. This involves raising the level of labor remuneration to the world standards. To ensure the sustainable development of the region, an optimal competitive environment is needed. Therefore, the relationship between the innovative development of the Russian economy and the level of market competition has been revealed. Measures for increasing innovative activity in industrial regions are proposed.
Procédés et opérations des sujets parlants chez F. de Saussure
Authors: Testenoire Pierre-Yves
Published: June 2018

La rupture proclamée par Saussure avec l’approche psychologique du langage, relayée par sa lecture structuraliste, ne doit pas dissimuler l’importance accordée dans sa théorisation à l’activité cognitive des locuteurs. En effet, la critique de la psychologie chez Saussure va de pair avec une définition de la langue en synchronie par la conscience des sujets parlants. C’est dans ce cadre que sont développées, dans les cours de linguistique générale, les notions de « procédé » et d’« opération des sujets parlants » sur lesquelles porte cet article. On s’intéressera à la carrière de ces notions mobilisées pour l’analyse de faits morphologiques et syntaxiques et spécifiquement la construction de ce que Saussure appelle les « entités abstraites ».
De Culioli à Saussure, aller-retour
Authors: Ducard Dominique
Published: June 2018

La linguistique de l’énonciation développée par Antoine Culioli est une théorie des opérations prédicatives et énonciatives. Les deux concepts d’opération et de représentation sont ainsi au cœur du modèle épistémologique et de la méthode d’analyse, qui cherche à démêler les relations en jeu dans la construction des énoncés pour les rapporter à l’activité symbolique de représentation et au processus mental qu’elle présuppose. Un examen critique du modèle des trois niveaux de représentation nous amène à distinguer la fonction de représenter du mode de représenter. Le retour à Saussure nous permet de revoir le modèle en y intégrant, au niveau des représentations notionnelles, ce que celui-ci nomme des figures. Une brève étude de cas illustre, pour finir, le développement théorique.
