The article considers one actual method for development coal deposits in the Kuzbass by open-underground mining. The scientific and practical advantages of the proposed method due to the use of common infrastructure of coal mine and a modular mine site (subsequently transformed into a mining and technological structure operating according to the mine – longwall scheme) are presented. Currently, a development strategy for Kuzbass until 2035 has been developed. As part of the strategy, a draft program for subsoil use is being formed in the coal industry department. The program should take into account all the positive and negative aspects associated with coal mining in cities and municipal areas and also their prospects. In the Kuznetsk coal basin, 42 mines and 52 opencast mines are mining, of which 12 enterprises use partially unified infrastructure. According to the results of open-underground mining work conducted by the laboratory of the Institute of Coal and Coal Chemistry of the Siberian Branch of the Russian Academy of Sciences (Institute of Coal SB RAS), the list of sites includes favorable mining and geological conditions with incidence angles of up to 18 degrees. As open-pit coal production increases, many sites encounter such a parameter as maximum allowable (boundary) strip ratio. At the stage of preparing the feasibility study for the development of a coal deposit, this coefficient is calculated first of all, since duration of enterprise’s work and its economic component depend on it. In order to increase parameters, it is necessary to carry out transition from open works to underground. As a result, coal mine will not work at a loss, providing production with an economically disadvantageous strip ratio.

Abstract As a controllable active resource in China, coal mining is facing the transition from output to quality. Base d on the total mining production and average capacity, the current situation and level of coal mining at three scales of mine, city and province is analyzed , data support for the layout of sustainable mining development and the optimization of output is provided. The results show that China's coal is mainly mined by underground mining, accounting for 87%, with an average production capacity of 0.93 million tons. Open pit mining accounts for 13%, with an average production capacity of 5.73 million ton s. S o t he average production capacity of open pit and underground workers is 1.045 million tons, with 1,181 coal mines capacity lower than 0.3 million tons, accounting for 35% of the total coal mines, contributing only 4% to their output. They are distributed in about 48 cities in 6 provinces, seriously restricting the green coal mining. The coal industry should speed up the reduction of small coal mines in key provinces and cities, eliminate outdated product ion capacity in the central region, increase the speed and proportion of coal resources moving westward, and promote high quality development of coal mining.

Coal mining is one of the key mining industries in Vietnam. Coal is also an important fuel formany other industries. Currently, coal mining is mainly concentrated in Quang Ninh coal basin, theproportion of open-pit coal mining and underground mining is quite similar. However, according toDecision 403/QD-Ttg on approving the adjustment of the Vietnam coal industry development plan up to2020, considering the prospects by 2030, the mining output will be from 51 to 54 million tons by year2025 and from 55 to 57 million tons by 2030. In which, the proportion of underground coal mining willincrease gradually compared with that of open-cast mining, specifically, by 2030, the proportion of thelater compared to that of the former will be only 11%. According to this plan, open-pit coal mines havebeen shifting to underground mining technology, due to the increasingly deep conditions of coal seams.The following article will analyze the current status of coal mining in Vietnam and some highlights of thecoal industry development plan to 2030, in order to provide a general picture of Vietnam’s coal industryin the future.

Abstract With the depletion of shallow coal resources in China, the depths and scales of mining have increased. For several coal mines, the extraction has changed from open-pit to underground. Due to open-pit and underground mining disturbance, landslide disasters frequently occur at high and steep slopes of open-pit mines. The effective identification of danger zone of slope and accurate determination of corresponding stability is important in the field of geotechnical engineering. Herein, Antaibao open-pit coal mine was employed as the research object. Firstly, as per the composition and structural characteristics of on-site slope rock mass, six typical disaster factors were summarized, while the assignment criteria for discrete and continuous variables were divided according to the landslide body characteristics and spatiotemporal distribution. Thereafter, based on the comprehensive evaluation principle of fuzzy mathematics, high and steep side stability in the multi-factor influence regions was comprehensively evaluated, while the spatial division of the unstable region was determined. Finally, the slope potential slip surface in the unstable zone of the western side was utilized as the calculation model object, and sensitivity analysis of the slope impact factor was conducted using the MSARMA method. Therefore, the earthquake as well as drainage rate (groundwater dynamics) were determined as the sensitivity factors. The numerical simulation of FLAC3D finite difference method was performed to analyze the evolution law of displacement field under natural, seepage, and vibrational conditions of the northwest slope.

The article deals with the development of coal industry of the Donetsk basin and technical support of mineral fuel production in the mines of the region in the late XIX - early XX centuries. The last decade of the XIX century. characterized by the concentration of coal enterprises, which led to the widespread implementation of steam lifting, drainage and ventilation devices, the use of dynamite instead of gunpowder in the conduct of underground mining; construction of better equipped and capital super-mine technological complexes. It is noted that the coal mining enterprises of Donbass in 1914, although technically lagging behind the leading capitalist countries, were relatively modernized and showed positive tendencies to their further improvement.One of the major drawbacks of the beginning of the development of the Donbass coal industry was the lack of advanced machinery.  By the middle of 1914 at least 12 types of felling machines were already actively used in the mines of the Donetsk basin, moreover, the supply of disk and rod machines was carried out by British factories, chain - American, shock - British, American, and German. Cutting machines belonged to the heavy type and cost several times more than percussion. Cutting machines were driven by pneumatic or electropneumatic engines. It was emphasized that miners in search of maximum optimization and productivity of coal mining were increasingly concerned about the technical improvement of their enterprises, as the introduction of appropriate innovations could significantly affect the economic feasibility and profitability of enterprises. This was required by the technological necessity in connection with the expansion of production and the constant shortage of labor. Foreign owners and shareholders who tried to introduce advanced technologies of their countries played an important role in the implementation of innovations. In addition, technical improvements in mining processes not only brought economic benefits to their owners, but sometimes indirectly improved working conditions and safety at mining facilities.

The article features the problem of residential development that migrant workers had to face in the mining districts of the Kuznetsk Basin during the first five-year plan. The author identified the causes of the housing crisis in the early 1930s that forced many independent miners to abandon mining enterprises. The paper describes the agenda taken by the central government authorities of Donbass and Kuzbass in order to provide miners with housing. It focuses on the types of housing in the Kuznetsk Coal Basin according to the method of production and building patterns, including communal houses. Prefabricated standard wooden constructions made it possible to build a lot of houses in a relatively short period of time. The main mistakes included a poor material base, limited workforce, and a shortage of building materials. As a result, the initial construction program was never fulfilled. The research focused on the residential development of the coal mining town of Prokopyevsk, its types of dwellings, the number of citizens involved in mining provided with state-owned housing, and the average housing space per capita. Thanks to the housing commissioned, the housing stock was significantly increased in the coal industry in general, and, more particularly, in the Kuzbassugol coal mining trust. The extensive residential development was not aimed at improving the living conditions of miners and their families but at binding migrants to their mines in order to meet the coal-mining program of the first five-year plans.
