This article describes the methods of developing and increasing the operational efficiency, which are implemented at production units of the SUEK-Krasnoyarsk JSC. It is demonstrated that their rational combination and mutual complementation in modern conditions of rising competition among coal producing companies, emergence of new challenges and higher requirements for the development dynamics of coal producing companies allow to efficiently use the production potential of enterprises and the labour potential of their employees. As a methodological approach we use the process and project approach to facilitate the development of enterprises that are part of a regional production association. The practice of solving the task of increasing the operational efficiency at production units demonstrates the necessity to form an incentive environment for developing both employees and enterprises at the enterprises and in the association. The goal of this environment is to provide systematic activities related to increasing the involvement and business activities of the personnel in the processes of production activities, in the development and implementation of actions aimed at improving and optimizing the production processes.

Pyrite copper-zinc (sulfide) and polymetallic ores in Russia are complex and rebellious mineral raw materials. The main processing technology for such ores is flotation. Enhancement of the flotation technology for such mineral raw materials is currently performed in several directions. The practice of copper-zinc ore processing proves that obtaining highquality zinc and pyrite concentrates is impossible without the use of various modifiers in the sphalerite and pyrite flotation process. Such reagents are copper (II), zinc and iron (II) sulfates in the alkali-calcic medium. Therefore, research was carried out to study floatation properties of sphalerite and pyrite in the alkali-calcic medium with addition of one of the indicated sulfates to the mineral flotation process. The effect of each of the sulfates of copper (II), zinc and iron (II) on the flotation properties of sphalerite and pyrite was studied during flotation of the mineral with butyl xanthate and dithiophosphate at pH equal to 8, 10, and 12. The aim of this work was to study the effect of the sulfhydryl collectors in presence of copper sulfates, zinc and iron for flotation of sphalerite and pyrite with the grain-size class of 0.074 + 0.044 mm from one of the Russian deposits.

Methodology of designing pilot tests in open-pit mining is a complex and insufficiently developed issue in the theory and practice of designing mining systems, which, as a rule, fails to take into account the mining and geological features of the deposits. The complex development of mineral deposits requires new methods of open-pit designing. Thus, the theoretical justification and development of the methods to determine the optimal parameters and indicators of open-pits during the design of pilot tests with the establishment of scales, deadlines, tasks and test conditions is an urgent research problem. The authors of the study have systematized the research trends in developing the basis for designing pilot tests in open-pit geotechnology. The level of geological inaccuracies in case of insufficiently reliable prospecting results leads to a decrease in the expected technical and economic indicators of the mining project ranging from 5-20% to several folds. When information on the deposit is insufficient, pilot test projects are prepared. This is done in order to obtain additional input data for preparation of the feasibility study of permanent conditions or at the stage of the field development to verify the created technologies and means of their mechanisation in order to avoid revision of the mining system parameters in the course of the field operations due to discrepancies between the geomechanical and hydrogeological representations given in the detailed exploration materials and the real conditions.

The article discusses methodological aspects of designing semi-stationary and mobile crushing and transfer units (DPU) carried out by the experts of Uralmashzavod PJSC and IGD Ural Branch of the Russian Academy of Sciences on behalf of the Russian Metalloinvest company during the development of the Russian DPU-7200 model. As the result of the R&D work performed, a DPU was manufactured and installed at a mining operation as part of the in-pit crushing and conveyor (IPCC) systems, which is intended for conveyor transportation of ore from the open pit. A distinctive feature of the discussed DPU is that it is made as a complete system with the supporting steel structures integrated in its design, which makes it possible to relocate it during the service life when expanding the IPCC. The issues concerned with justifying the DPU layout, parameters of the receiving and unloading hoppers are discussed with account of structural, strength, mining and technological factors. The paper presents the technical characteristics of the developed DPU, as well as the design features of the primary equipment. The impact of the related technological factors, i.e. irregular character of dump truck traffic, the technological and temporal modes of the IPCC operation in general and those of the DPU in particular, the designed schedule of maintenance and repair, etc., is shown.

Presence of tectonically weakened and disturbed zones leads to decreased underground excavation rates and reduced safety of the mining operations. As a rule, such zones are bounded by vertical and subvertical disturbances that contribute to weakening and loss of stability of the rock and ore mass. Disturbance of the natural state, in particular driving of a mine workings, provokes irreversible deformations due to redistribution and concentration of stresses within the boundary rock mass, which is more rigid. At the same time no significant stresses are formed within the rock mass of the tectonic zone due to its caving. Therefore, when developing solutions for driving and supporting mining excavations within the tectonic zone, the rock mass should be considered as weakened and highly fragmented with unbonded structural blocks. The particle-size distribution within the rock mass of the tectonic zone varies in a wide range of sized from several to tens of centimetres. In this context, the mining and rock reinforcement technology presented in this paper accounts for the possible free caving of the non-bonded host rock mass made up of small-sized blocks. The paper discusses physical and mechanical characteristics and the stress-and-strain state of the rock mass within the tectonically weakened zone and the boundary host rocks, and a technology of driving and supporting underground mine workings is proposed on this basis.

Emissions of the greenhouse gases, particularly methane and carbon dioxide, by the mining, processing, and energy industries can significantly affect pollution in the bottom layer of the atmosphere, aerosols, and the atmospheric greenhouse effect. Continuous monitoring of emissions is the basis for developing effective strategies to reduce greenhouse gas emissions. Satellite missions are actively used for this purpose. The article provides an overview and description of the existing databases of greenhouse gas emissions obtained based on satellite measurements. The monitoring methodology involves satellite spectroscopy aimed at analyzing the spectral characteristics of light absorbed by the atmosphere. The results of measurements by satellite spectrometers show the total molar mass of substances throughout the atmospheric column. Global satellite monitoring allows identifying zones of anomalous concentration and identifying new sources of greenhouse gases, comparing them with the ground-based measurements of pollutants.

The article discusses the issues of strengthening the mineral resource base of non-ferrous metallurgy by introducing ore processing wastes into the production cycle. The relevance of the study is explained by the decreasing availability of mineral resources. The conventional ore processing technologies increase the volume of processing tailings in storages. Waste-free disposal of primary processing waste is not developing, and this waste is often used without extracting metals from it to match the sanitary requirements. The acute environmental problems are aggravated primarily by the lack of leverage for centralized accounting and regulation of the accumulated waste. The efficiency of leaching technologies is proved by a comprehensive method that includes experiments and calculations with a comparison of processing options. Quantitative values have been obtained and dependence diagrams of metal extraction on the contributing factors have been plotted, which make it possible to characterize the processes of leaching the mill tailings using a disintegrator. It has been proved that during the mechanochemical activation of the leaching process, metals extraction exceeds the extraction efficiency of the conventional waste processing technologies and ensures a safe level according to the sanitary requirements. It is determined that the mechanochemical activation in the disintegrator during metal leaching increases the strength of concrete mixtures based on secondary tailings. It is concluded that activation of the leaching processes in the disintegrator ensures the extraction of 50 to 80% of the previously lost metals from the mill tailings. The development of man-made deposits with innovative technologies with metal leaching is a real step towards expanding the mineral resource base of metallurgy and improving the environmental situation in the mining regions. Unlike the technologies related in terms of the application area and the purpose, the discussed technology enables waste-free processing of ores.

The paper discusses the different shapes of diamond segments for stone cutting machines. The purpose of this research is to find ways to improve the abrasion resistance of the diamond segments, reduce the vibration load and increase the cutting efficiency. The operating conditions of stone-cutting machines are analysed, as well as the ways of increasing the efficiency of diamond segments by changing their shape. A calculation of the loads arising during operation of the diamond segments is made, and the results are verified using an experimental setup. The initial shape is analysed and the stresses that exceed the material parameters are found. In order to reduce the stresses, a diamond segment with rounded edges is simulated. Segments with bevelled edges and conical shape are also considered. Based on the experimental results, it is found that one of the promising shapes is that with rounded edges.

The article considers the possibilities of developing an automated system for monitoring and predicting the technical condition of in-pit vehicles at the operation stage based on failure statistics and network analysis of data received from health sensors of the mining machines. This study seeks to reduce emergency downtime in the mining industry by introducing modern information and communication technologies. The applicability of existing methods to analyze digital signals received from the sensors installed on the mining equipment was assessed. A promising approach is considered, using the progress achieved in network engineering and conversion of the time series signals into the integrated networks. A sequence of operations is proposed as an innovation, including collection and analysis of data, development of network prediction models and practical implementation of the results. It is expected that using such a sequence of steps will be able to promptly notify of the need to repair equipment, thereby reducing downtime, which in turn will increase productivity and reduce the operating costs. The main stages of the study are formulated and presented, the implementation of which is aimed at predicting the health of the equipment, identifying the need for unscheduled repairs, which will lead to a decrease in the number of emergency failures or their prevention in real operating conditions of mining enterprises.

A review is made of the current global trends in energy generation. Directions for diversifying energy generation sources are proposed, e.g. using both imported and coal seam gas as well as hydro resources along with coal. CONCLUSIONS. Focusing on only one energy source reduces the energy security of the region. Energy shortages and the presence of costly diesel-based power generation hinder the economic development of the Republic of Tyva. In the republic that has extensive coal reserves, coal generation has to introduce modern “clean coal” technologies. A high share of thermal power plants in the structure of the coal-fired generation capacity will allow the development of cogeneration using innovative, environmentally friendly Russian technologies. Options for solving the challenge of energy shortage in Tuva in the future until 2035 are proposed.
