PROSPECTS FOR SURFACE MINING OF IRON ORE DEPOSITS IN UKRAINE
Authors:   Kryvyi Rih National University, Ukraine, Slobodyanyuk Valeriy
Published: February 2022

At present, new iron ore deposits with much more favorable mining and geological conditions than in Ukraine are being commissioned abroad. Factors that currently complicate the operation of iron ore pits in Ukraine are the significant amount of stripping operations and the need to alienate large areas of agricultural land to place waste dumps. The purpose of this study was to determine the parameters of the most typical iron ore deposits, surface mining of which is possible in the future. The geometric dimensions and depositional conditions of iron ore deposits largely determine the main parameters of the open pit, its production capacity, development system, the method of opening-up and the key performance indicators. It was found that the stratified deposits are 82.5% of reserves of ferruginous quartzite and 83.3% of the total number of deposits, synclinal deposits - 3.3% of reserves and 8.3% of deposits, anticlinal - about 14% of the balance reserves and 8.3% of the number of deposits. 50% of ferruginous quartzite reserves are represented by deposits with a horizontal thickness of over 200 m. The performed mining and geometric analysis of iron ore deposits is the basis for the development of new surface mining technologies, which will ensure the costefficient development of ferruginous quartzite deposits with complex mining and geological conditions.

As a way of exploitation in mining operation, mass blasting has the more application. However, usage the large amount of explosives leads to increasing the negative blasting effects. By the negative blasting effects, we mean seismic effect of blasting, sound effect, scattering of blasted rock mass, etc. In order to protect environment from shock when performing blasting it is necessary to define rock mass oscillation equation for each working site. This paper offers the analysis of the method for defining parameters of the oscillation equation. To define parameters in the rock mass oscillation equation, we have used five models. The first model represents a usual model – method of Least Squares. The second model is based on the quotient of the value of the equal number of experimental data of oscillation velocity and corresponding reduced distances. The third model is based on defining parameters of oscillation equation by applying Lagrange’s theorem. The fourth model is based on defining parameters for oscillation equation by applying the quotient of relative oscillation velocity increments and reduced distances. As the result of numerous measuring’s there has been noted that the value of one of the parameters in the oscillation equation is within the limits from 1 to 3, however most frequently from 1 to 2. On the basis of this as well as on the basis of oscillation equation characteristic, the value of one parameter was adopted. Thus, we got a new rock mass 292 oscillation equation which is now simpler, and we designated it as the fifth model. On the basis of calculation on concrete example of mass blasting, it has been stated that all mentioned models may be used in order to calculate rock mass oscillation velocity

Published: February 2022

A comparative analysis of the characteristics of DRGs used in opencast mining in Ukraine is given. Experimental studies of the influence of drive systems and drill rigs on the dynamics of the drill process were carried out in the mining and geological conditions of the Central Mining and Processing Plant (Kryvyi Rih, Ukraine). Frequency characteristics and analysis of dynamic properties of automated drive systems and frequency characteristics of transmissions of the rotation 369 mechanism are obtained. The behavior of natural frequency oscillations in closed control circuits of rotary actuators was studied and it was found that they cross the cutoff frequency and fall into the bandwidth from the attenuation band in frequencycontrolled asynchronous motors of new generation drill rigs when using the maximum number of connected tubes in the drill rod. It is established that the lowest oscillation frequencies due to the lateral frequencies generated by the oscillations of the drill rod fall into the fastest internal current loop. The purpose and objectives of research is energy and resource saving in the process of drill subsoil wells by concentrating the flow of mechanical power in the bottom hole zone and ensuring minimum dynamic loads in the drill machine in the presence of elastic connections and variable natural frequencies in multi mass transmission with concentrated and distributed parameters. The object of the study is the frequency compatibility of electromechanical processes in the electric drive rotation of the drill rig with distributed parameters taking into account the change of attached distributed and concentrated masses to the transmission. The subject of research is the elastic properties of transmissions, frequency characteristics of control systems and their mutual influence on the quality of work in electric drives.

Authors: Fachrudin Arif Rochman
Published: February 2022

Heat pipe merupakan salah satu alat penukar kalor yang memungkinkan pemindahan sejumlah kalor melalui luas permukaan yang sangat kecil.  Heat Pipe mempunyai peran penting dalam sistem pendinginan salah satunya dalam komponen elektronika. Dengan sistem pendinginan maka temperatur komponen akan terjaga sehingga terhindar dari kerusakan kerusakan yang diakibatkan dari panas yang berlebih (over heating). Heat pipe terdiri dari tiga bagian, yaitu evaporator, adiabatis dan kondensor. Kedalam pipa itu diberi fluida kerja yang berfungsi membawa panas dari evaporator dan melepaskannya di kondensor.  Di bagian Evaporator, panas dari komponen yang didinginkan diserap dan dipindahkan ke ujung yang lain yaitu bagian Kondensor untuk dilepas panasnya dilingkungan. Heat pipe mempunyai prinsip yang hampir sama dengan thermosyphon, perbedaannya adalah di heat pipe menggunakan dinding wick.

Kegiatan penelitian ini bertujuan mengetahui sejauh mana kinerja termal dari heat pipe sebagai penukar kalor dengan variasi panjang kondensor. Heat Pipe didesain dengan variasi panjang kondensor sebesar 44 cm ,66 cm,88 cm,110 cm dan 132 cm..

Hasil penelitian menunjukkan bahwa, Tahanan thermal tertinggi pada panjang kondensor terpendek pada tempeatur 400C (14 C/W) dan terendah pada panjang kondensor terpanjang pada temperatur 1200 C(1 C/W). Pada semua temperatur, semua variasi panjang kondensor maka daya output dan fluks kalor akan semakin besar.  Pada panjang kondensor ukuran yang  sama dengan evaporator, semakin tinggi temperatur, maka semakin besar fluks kalor dan daya output. Proses pada eksperimen ini paling efektif pada panjang kondensor 1,25 kali (132 cm) dari panjang panjang evaporator, karena setelahnya nilai tahanan termal dan daya output akan mengalami kecernderungan tetap.

Published: February 2022

Interpretasi produk perencanaan sebagai panduan pelaksanaan bisa terjadi kesalahan. Kurangnya kemampuan ahli tenaga teknis, keterbatasan alat dan bahan serta metode pelaksanaan yang salah sebagai factor penyebab kesalahan tersebut. Sebagai contoh adalah kesalahan pelaksanaan pemancangan tiang pada pembangunan Gedung lantai 8 di jalan Veteran Banjarmasin.

Berdasarkan hasil investigasi lapangan menunjukkan bahwa titik berat (As) pile cap atau As beban struktur atas rencana tidak satu sumbu dengan As group tiang yang terpancang. Kondisi tersebut mengakibatkan kegagalan dukung tiang karena tiang mengalami over load dan uplift . Oleh sebab itu perlu dilakukan redesain kapasitas dan distribusi beban ke tiang akibat eksentrisitas berlebih. Langkah-langkah awal dapat dilakukan dengan pengumpulan data pendukung dan dilanjutkan dengan penyelidikan data utama seperti posisi koordinat tiang terpasang dan koordinat As pilecap. Data-data tersebut dianalisis dan diolah menjadi redesain formasi group tiang yang mampu memenuhi syarat kapasitas dan distribusi beban rencana ke tiang.

Hasil pengukuran menunjukkan bahwa eksentrisitas arah y maximum terjadi pada jalur C sebesar -0.486 m dan minimum pada jalur A sebesar  0.010 m. selain itu eksentrisitas maximum arah x terjadi pada baris 4 sebesar -0.430 m dan minimum pada baris 6 sebesar  -0.027 m. Eksentrisitas eksisiting tersebut lebih besar dari eksentrisitas ijin e > B/6 per pilecap. Kondisi eksentrisitas eksisting tersebut mengakibatkan tidak tercapainya safety factor (SF) rencana 2,5 dan terjadinya overcapacity (Pmax 208 ton) serta tiang tarik.

Daya dukung tiang group existing maximum sebesar 944,55 ton dengan SF minimum yang terjadi 0,965 <  SF rencana 2,5. Setelah dilakukan redesain jumlah dan posisi tiang diperoleh ex maximum 0,187 m dan ey maximum 0,104 m < e ijin B/6 dan  daya dukung tiang group redesain maximum sebesar  1620,17 ton dengan SF minimum 2,354 ≈  SF rencana 2,5.

Redesain tersebut menghasilkan distribusi beban ke tiang P max 83,30 ton dan P min  57,32 ton. Distribusi tersebut tidak mengakibatkan overcapacity dari P ijin 208 ton dan tidak menimbulkan tiang tarik. Hasil re-eksentrisitas dan perhitungan daya dukung tersebut dituangkan dalam shop drawing redesain titik pancang sebagai panduan pelaksanaan di lapangan.

The purpose of the work is to analyze the modern screening diagnostic tests used in the outpatient practice of a pediatrician in conjunction with classical diagnostic methods. To assess the significance of screening diagnostic tests in a differentiated approach to therapy and health improvement of children, in order to reduce the unjustified prescription of antibacterial drugs. To highlight the main advantages of screening diagnostic tests. To determine the scope of their application in outpatient practice. To characterize the available modern screening approaches in the work of a pediatrician. Results. In recent years, medicine is increasingly interested in the issues of introducing rapid diagnostic tests into the outpatient practice of a pediatrician. The speed of obtaining a reliable result when using rapid tests makes them the optimal tool for mass screening, since the sensitivity of rapid tests reaches 95% and the specificity is almost 100%. The obtained test results allow a district pediatrician to quickly make a decision on early diagnosis and therapeutic tactics in an urgent situation. Accessibility of use, minimal training and the ability to visually evaluate the results significantly reduce the number of errors at the preanalytical phase. Conclusion. This methodological approach is undoubtedly valuable in the work of pediatricians, especially in an outpatient network. Their active implementation into everyday practice makes it possible to predict the course of the disease at the earliest stages of its development and to differentiate the appointment of therapy in each personified case.

The experience of 811 bronchoscopies (100%) was analysed in patients on artificial lung ventilation. The position of the intubation tube in the trachea during the procedure was assessed. In 78 cases (9,618%) there was an incorrect position of the intubation tube requiring correction. In 35 cases (4,316%), the intubation tube was displaced to the right main bronchus and as result, the left lung was not ventilated. In the remaining cases, various ways of the incorrect position of the intubation tube above the tracheal bifurcation carina were noted. As a recommendation, endoscopic criteria of the correct position of the intubation tube are suggested.
