- Abstract:
- The article deals with topical issues of mineral resources development on the Arctic shelf of Russia using innovative autonomous mining complexes. Special attention is paid to the study of the relationship between sea water density and depth as a key factor affecting the efficiency of subsea equipment. The authors proposed an original technical solution - an autonomous mining complex using compressed gas energy for extraction, processing and transportation of minerals. A mathematical model has been developed that allows to calculate the lifting force of the autonomous mining complex taking into account changes in water density at different depths. The practical significance of the study lies in the justification of the choice of working gas for an autonomous mining complex and the creation of calculation models applicable to the design of underwater mining operations. The results of the work can be used to optimize technologies for the development of mineral resources in the Arctic.

- Abstract:
- The article presents the results of studies to substantiate the optimal parameters of excavator-automobile complexes using mechanical shovels (EAKML) for the conditions of the Kuzbass sections. A number of tasks have been solved in the work: a unified formula has been developed to determine the performance of modern mechanical shovels with a bucket capacity of 6,3 to 55,8 m3 of the weighted average size of blasted rock pieces, the high reliability of which has been confirmed by comparing the calculated values with timing values obtained at the sections as a result of a pilot industrial inspection; an algorithm and methodology for determining the optimal parameters of EAKML was developed; graphical relationships were established between changes in the specific operating costs for the development of one cubic meter of overburden in the conditions of Kuzbass sections and the weighted average size of pieces of blasted rock when using mechlopats with a bucket capacity of 6,3 ÷ 55,8 m3 for rock categories IV and III; an express nomogram method was developed to select the type of excavator or their number in the design or planning of mining operations. The article presents the values of minimum costs and replacement productivity of mechanical shovels in the development of overburden rocks of categories III and IV of EAKML with a bucket capacity of 6,3 ÷ 55,8 m3 for the conditions of the Kuzbass sections corresponding to the optimal working conditions. These recommendations and the methodological approach presented in the work will be useful for both designers and planners of mining enterprises. The use of the results of the work will make it possible to determine the optimal parameters of excavator-automobile complexes using mechanical shovels when re-equipping a quarry to increase the economic efficiency of coal mining.

- Abstract:
- An urgent task for the oil and gas industry is improving the efficiency of hydrocarbon recovery from difficult-torecover reserves (DTR). The study aimed to investigate the influence of component composition and initial conditions on operational characteristics (combustion rate, volume of gaseous products) of composite solid fuels (MSF) with an ammonium nitrate composition (ANC) and to develop recommendations for their optimization for use in downhole gas generators. A neural network software module validated on experimental data was employed. It was demonstrated that pressure and charge density are key factors governing the combustion process. Compositions of MSF ANC adapted to typical conditions in Western Siberia, the Volga-Ural region, and the Arctic were proposed. The results align with the Russian Federation’s Mineral Resource Complex Development Strategy (MRC) until 2035 and ISO 14001 requirements.

- Abstract:
- The article presents the results of a multifactorial analysis of the main operations of the technological process of grinding mineral raw materials in ball, vibration and planetary mills, the relevance of which will increase as demographic, economic and other conditions change in the countries of the world. The grinding parameters are studied in laboratory and industrial mills operating in mining and processing plants and other workshops for the preparation of mineral raw materials by comparing samples of raw materials and unloading the mill using control sieves. The fineness of the grinding is carried out in a drum mill. Other parameters are investigated using generally accepted methods. It is established that the presence of numerous factors and the empirical nature of the quantities used do not allow the use of the available research base for solving problems of mechanical crushing and grinding. It is recommended to use the criterion of critical stress at impact, the velocity of elastic waves and the value of dynamic viscosity as criteria for the dynamic destruction of brittle media in the production of technological processes. It is shown that there is a stable correlation between the fracture coefficient and the size of the split surfaces during brittle fracture of rocks as a result of impact. It was revealed that the new concept of ore preparation should be based on the phase-structural properties of raw materials, the possibility of disclosure processes, and equipment parameters. Such a concept will be more consistent with the principles of humanization of relations in the «Nature – Man» system. The results of the completed multifactorial studies can be in demand in the development of existing modernized and under construction deposits of solid minerals in the mining industries, as well as in the training of highly qualified personnel in higher educational institutions.

- Abstract:
- In the course of the study, an analysis of technological safety solutions for deepening vertical mine shafts was carried out. Methodological approaches to risk assessment and design of protective structures taking into account the specifics of underground space have been developed. An innovative safety device is proposed, which competes with the safety pillar in terms of dismantling efficiency. The implementation of this solution allows you to optimize the production process and reduce operating costs while maintaining a high level of safety. On the basis of the studied data and theoretical calculations, the optimal design parameters of protective devices are determined, ensuring the maximum efficiency of their functioning in the conditions of underground mines under various types of loads.

- Abstract:
- Underground mining of coal deposits is accompanied by many risks, one of which is spontaneous combustion of coal, leading to many negative consequences. Therefore, in order to prevent the negative impact of emerging risks, surveying observations of deformations of the Earth’s surface, which are the result of underground fires, are carried out. The paper highlights the issues of introducing the radar interferometry method into a complex of surveying operations to monitor deformations of the Earth’s surface in the coal mining area. The article discusses the characteristics and operating principle of radar interferometry. An example of a study of the relationship between underground fires and resulting deformations of the Earth’s surface is presented. The scheme of application of radar interferometry in the surveying monitoring of vertical subsidence of the Earth’s surface is shown. An algorithm for performing surveying operations using radar interferometry is proposed in order to detect spontaneous combustion of coal. This article will be a material for the development of further research on the characteristics of radar interferometry and its application in surveying activities.

- Abstract:
- Waste incineration plants (WIPs) are currently becoming an important element of the integrated municipal solid waste (MSW) management system in Russia. This article examines the issues of processing and transformation of products formed during MSW incineration in the environment. The results of a comparative analysis of literature data on the presence of pollutants in slag and ash residues from MSW incineration are presented, from the perspective of the environmental and hygienic aspects of their disposal or storage. Slag and fly ash from WIP No. 3 were taken as the object of research. In order to determine the possibility of safe use and disposal of these wastes, the presence of pollutants in slag and ash residues was determined using a complex of mineralogical and analytical methods. An unambiguous conclusion was drawn about a significant excess of heavy metal content in fly ash (in relation to hygienic standards for soils), and a high migration capacity of heavy metals from ash to soils and into surface and groundwater sources was demonstrated. A comparison of the contents of heavy metals and trace elements in aqueous extracts of slag with the maximum permissible concentrations (MPCs) of chemical substances in water bodies showed that, for all major environmentally controlled elements, the concentrations are much lower than the MPCs. The results of leaching tests on the studied slag indicate that the transfer of heavy metals from the slag is practically non-existent, which means that the slag is stable and may be suitable for recycling without any restrictions.

- Abstract:
- Almost half of Russian surface mines produce coal in the methane zone. This actualizes research in the field of methane concentration control in the working zone of the open pit, as well as in the sanitary zone. There are point, linear, and area sources of methane at surface mines. The key parameters affecting methane distribution are terrain conditions, shape of the cut and airflow direction. Possible methane concentrations were estimated for an average cut operating in a methane zone with airflow direction along the length of the cut and perpendicular to it. Drilling and blasting wells, coal and host rock outcrops, and transported mineral flows were considered as sources of methane. It was revealed that at the boundary of the sanitary zone methane maximum permissible concentration exceedance is not expected. It has been determined that ventilation units provide the necessary amount of air to dilute the methane. In this regard, the emphasis when choosing measures to intensify mass transfer was placed on the geometric parameters of the section, as well as on the power and energy consumption of installations.
