The current state of underground coal mining technology in Russia and abroad is characterized by an increase in the load on mine faces and an increase in the pace of conducting preparatory workings. Between 2000 and 2014, Russia experienced a 16% increase in underground coal production. The daily load on the mechanized cleaning face (MCF) increased from 1,324 to 4,267 tons, i.e. by 3.2 times; the worker's productivity increased almost twofold. In some Kuzbass mines (Listvyazhnaya Mine LLC, Chernigovets Branch OJSC - Yuzhnaya Mine, SUEK OJSC Kuzbass») the average daily load on the KMZ is 9 ‒ 10 thousand tons, i.e. 2 ‒ 3 times higher than the average for the basin. However, many mines operate with a load of 0 ‒ 5 thousand tons per day. The main reason for the unstable operation of the KMZ mines in Kuzbass compared to the performance of high-performance domestic and foreign mines is the insufficient adaptability of modern Russian and imported technical equipment and technology.

The drilling and blasting method of rock destruction is the most effective and the only possible method for the destruction of strong ores and rocks. The efficiency of the explosive preparation of the mineral resource and the surrounding rocks for excavation determines the technical and economic indicators of the drilling and blasting complex, the productivity and safety of the following mining processes and the entire enterprise. The main method of explosive preparation of the rock mass for excavation is the production of mass explosions of well charges. Total mass of explosives The explosive capacity is 50-300 tons, and in some cases reaches 700 tons. Such a weight The blasting headquarters refers to both the open mining method and the underground one. Recently , concentrated charges in rising workings with a mass of have become widely used in underground mining 20 – 30 t and in beam well charges 2 – 3 t per charge. Seismic vibrations are one of the harmful manifestations of m 

In various branches of the global industry for the movement of bulk bulk materials Millions of conveyor systems, including belt conveyors, are used for cargo, materials, and rocks . The dispersed differences of the transported rocks intensively adhere to the belts, and when the idle (lower) branch of the belt interacts with the supporting rollers, these differences fall to the floor and gradually fill up the entire conveyor space. This leads to a complete failure. the conveyor is in operation. Constant manual cleaning bayonet from under the conveyor − It's a very difficult one., laborious and traumatic work. To prevent conveyor bulging and its consequences, the belts are cleaned structurally with the simplest devices, scrapers, after bending the loading drum. However, practice has consistently shown the low effectiveness of their use. Therefore, in many industrialized countries around the world, research and development work has been carried out for a long time to create more reliable and efficient 

On the northeastern slope of Salair, the Lochkov-Prague mosses were studied in the area of Guryevsk. In the Tolstochikha quarry, in the upper limestone package of the Tomchumysh suite, the mosses, first discovered by E.A. Elkin, are represented by Lioclema netshlavense Astr. (determined by G.G. Astrova). The species Liocle ma netshlavense Astr. is found in the upper part of the Borshchov horizon of the Lokhkovsky stage of Podolia [1] and in the same-age deposits of the North-Eastern Balkhash region [2]. Later, in the Tolstochikha quarry, Cyphotrypa variabile Mesent. [3] was found in the upper limestone package of the Tomchumysh formation, and in In the Staroguryevsky quarry, in the clay limestones of the Krekovo horizon, there are isolated colonies of Anomalotoechus sp. of poor preservation. Thus, in the stratotype sections of the Lokhovsky stage of the North-Eastern Salair,[4] the bryozoans are represented by Lioclema netshlaven se Astr., Cyphotrypa variabile Mesent., Anomalo toechus sp. In the dry suite and deposits of the Pet tsevsky horizon of the Lokhovsky stage.

The requirements applied to modern technically advanced mines are constantly changing towards becoming more stringent as the depth of mining operations increases.

An audit of the 20GFL steel smelting process in DSP-6 arc furnaces at the Rubtsovsk branch of Altaivagon JSC revealed issues related to defective steel due to mechanical properties. Despite the chemical composition of 20GFL steel being within the limits established by GOST 977-88, there were instances where the mechanical properties of the samples tested did not meet regulatory requirements.

The accuracy of calculations of energy and force parameters of various metal processing processes by pressure depends to a large extent on the accuracy of determination of the value of the resistance to deformation (flow stress). The value of the flow stress depends in general on the type of crystal lattice, chemical composition, structure, degree of deformation, temperature and rate of deformation.

The accumulation of humanity's intellectual potential in the last quarter of the 20th century allowed the resources of advanced countries to be mobilized to solve a number of global problems, such as: – The World Energy – to provide the global community with a single energy space; – The World Information – for the successful functioning of a single information space; – The World Transport (currently – multi-type) – to provide the global community with a single transport space. These global systems determine the successful existence of the global community as a single entity. However , the main problem remains unresolved – the construction of a "Worldwide Land Transport System", which includes connecting the Eurasian and American continents through the Bering Strait. Connection project the Eurasian and American continents Russia, the United States, as well as Canada and China should be considered as a historical

Ensuring safe working conditions during underground mining is one of the key challenges facing the domestic mining industry. This challenge is particularly pressing for Kuzbass, the country's main coal region.

Turbochargers are widely used in the chemical, metallurgical, and mining industries. Turbochargers are centrifugal compressor machines used primarily for This is especially true when large volumes of gas are supplied at a pressure of 0.15 ‒ 1.00 MPa. Compression occurs due to the release of gas by the working wheels in the radial direction under the action of centrifugal force. For greater efficiency, turbo compressors are made multi-stage: several impellers are mounted on a common shaft, separated from each other by diffusers. The stages are arranged in series, and the pressure of the compressed gas increases from the first to the last stage. Between some stages, the compressed gas is cooled in heat exchangers.

Matrix frequency converters have not received widespread use in the industry despite the obvious advantages over other types of converters. The main reason for this is the complexity of practical implementation, the lack of integrated power semiconductor switches capable of conducting current in both directions and blocking voltages of both polarities in the closed state, and a number of switching problems.

The purpose of this work is to analyze the results of the calculation of the building taking into account seismic impacts, develop measures to strengthen building structures, and analyze the results of the calculation of the reinforced building.

The city as an object of research, design and operation is constantly in the field of activity of many specialists: architects and designers, sociologists and economists, ecologists and dendrologists, geologists and transport engineers, etc., The task of builders is to coordinate the efforts of all specialists in order to give the city a functional and structural integrity. This work is carried out mainly at the research, design and construction stages. At the same time, an already built city remains "unattended." And it is now that the natural life of the "second nature" begins in it, and the development of the subject-spatial environment by man takes place. Traditions are born, social types of behavior are formed, and social and aesthetic values are determined. The urban environment is always unique in its character, not only in different cities, but also in different districts of the same city. The urban environment is a complex functional and spatial system.

The Scientific School "Information and Material Technologies in Electromechanical Systems of the Mining and Metallurgical Complex" consists of employees of the Scientific and Production Company INTECHSIB, the Departments of Electromechanics, Electrical Engineering, and Electrical Equipment at SibGIU. They work in the market of goods, works, and services for the mining industry. 

A significant increase in the volume of coal enrichment is accompanied by the generation of a large amount of waste – about 10 million tons per year. Coal processing waste (CPW) and coal mining waste are mine rocks and tailings from processing plants. They usually contain some amount of coal and clay component. All waste can be divided into two groups based on their carbon content. Carbon waste with a carbon content of more than 24% is rationally further enriched or used as fuel. The second group of waste contains carbon up to 24% and can be used in construction, metallurgy, and agriculture.

Kuzbass is one of the richest regions in Russia in terms of mineral reserves. Intensive extraction and processing of raw materials at local enterprises has led to the pollution of both surface and groundwater.

Kemerovo Oblast possesses both unique natural resources and significant industrial potential, and is of great importance for the country's economic development. The high concentration of industrial facilities within the region means that more than half the region's population is constantly exposed to air pollution, and water sources and central water supply systems pose a health hazard to residents. Therefore, it is important to study the region's environmental problems in a historical context.

The Kuznetsk Basin is the most industrially developed region of Siberia both in terms of the amount of coal reserves and its production. Currently, the region produces 56% of coal in Russia. According to the strategy for the socio-economic development of the Kemerovo Region, based on data from the Federal State Statistics Service, 174.0 million tons of coal were mined in the Kuznetsk Coal Basin in 2006, an increase of 105.2% compared to 2005. A particularly high growth rate is observed at coal enterprises engaged in open-pit mining. According to expert estimates, coal production will increase significantly in the future and by 2030 will amount to 275-330 million tons [1]. Consequently, the man-made load on the environment will also increase significantly.

The problem of energy conservation is one of the most important for countries in the Northern Hemisphere, and especially for Russia with its harsh climate. One of the main tasks is to increase energy efficiency and prevent heat loss during the operation of heat-generating installations during the heating season.

The main reason for the permanent reduction in the volume of ferrous metallurgy production in the city of Novokuznetsk, the metallurgical center of Siberia, over the past twenty years is the insufficient consumer demand for these products within a radius that ensures their competitiveness due to an acceptable level of transport costs.

The Russian economy needs to develop new management principles that facilitate its modernization. One component of economic management is oversight. The current economic management system does not meet modern requirements and is a significant constraint on Russian economic growth. According to RIA Novosti (December 25, 2014), M.A. Abyzov, a member of the Russian Government and Minister for Open Government, cites data indicating that the costs associated with ineffective oversight and regulation are estimated at approximately 2% of GDP. This is due to the duplication of certain oversight responsibilities. M.A. Abyzov believes that these costs can be avoided by shifting from monitoring compliance with norms and regulations to risk management. According to the minister, a risk-based model will be piloted in several federal executive bodies in Russia in 2015 (including Rostrud, Rostekhnadzor, and Rosobrnadzor).

At present, against the backdrop of an intensifying international process, security issues, especially security on a global, planetary scale, are becoming increasingly important.

Close international cooperation and dynamic business development erase state borders and contribute to the natural desire of mining specialists from different countries to exchange information, participate equally in joint projects, and mutually enrich themselves professionally and scientifically.
