Prospects for development of a technological structure of underground coal mines

The article discusses the issues of changing the technological structure of coal mines in accordance with modern trends in the development of underground coal mining technologies. Against the background of an increase in the level of concentration of mining operations, the longwall’s productivity, the stages of evolution of the technological structure of Russian mines, the results of the transformation of its technological subsystems and elements are considered. The creation of conditions for the realization of the production potential of modern highperformance longwall equipment is highlighted as the main direction of improving underground coal mining technologies. The main problems and ways of improving the technological subsystems of mines are shown. The necessity of solving the problem of limiting the longwall’s productivity by the gas factor and improving degassing technologies is emphasized. The features of the implementation of modern concepts of “Intelligent mine” and “Invisible mine” in underground coal mining are considered. An example of the successful implementation of individual elements of the “smart mine” concept at the mines of JSC SUEK-Kuzbass is considered. The necessity of periodic monitoring of compliance of the adopted technological and organizational decisions with the current mining situation and their compliance with the best available technologies of underground coal mining is shown. Perspective directions of development of the technological structure of modern coal mines have been identified, ensuring an increase in the efficiency of realizing the potential of modern high-performance equipment and increasing the competitiveness of the underground method of coal mining.
