Abstract: Currently, underground coal mining enterprises are faced with the issue of rational development of mine field reserves, in which the most attractive part of the reserves from a technological and economic point of view has been developed. Residual reserves require a more thorough development of the technological solution with an assessment of the economic efficiency of the planned work. One of the possible options for development, when considering a site of work with complicating factors that have formed during the overmining and undermining of the coal seam, which is planned for subsequent development of mine field reserves in the conditions of a coal mine. For clarity, a visualization of the impact of the formed hazardous zones is formed taking into account the mining and geological forecast, including zones of increased rock pressure on the extraction unit planned for the development of reserves. For timely control of safe underground mining operations and, if necessary, change of technological solutions, in terms of development of planned seam reserves, the first extraction unit to be developed is considered as an object for observation with subsequent formation of conclusions to justify the change of parameters of technological solutions for rational development of subsequent extraction units of the coal seam. The results of subsequent studies will facilitate prompt response to unpredictable complicating factors, which will allow adjusting measures for safe work in hazardous areas, improving the quality of the extracted mineral and ensuring complete extraction of reserves.
