Abstract

The main goal of the research is to improve the efficiency of underground coal mining in difficult geological conditions based on an integrated approach to the technological schemes designing, and the feasibility study of space-planning decisions. In conducting the research, the authors used a complex method, including synthesis and analysis of the theory and practice of the development of coal beds using underground methods; the analysis of the results of field studies of the underground working conditions in the high rock pressure areas; the experimental and analytical studies of the effect of high rock pressure areas on the state of excavation workings in the lavas at various parameters of technological schemes; computer data processing. The specifics of mining and geological conditions of mining operations in the Russian mines were analyzed. The issues of ensuring the efficiency of underground mining and a choice of rational space-planning decisions in complex mining and geological conditions were considered. Based on the computer modelling, the cost-effectiveness of different options for the development of mining operations in the conditions of the Alardinskaya mine was estimated. The necessity of taking into account the production effectiveness of the reserve extraction in the process of assessing the resource base of the mining enterprises was shown. The recommendations for the sustainable development of the coal-mining companies, taking into account the resource base efficiency, were given. The study results obtained can be used in the design of new mines and substantiation of space-planning solutions in underground mining of coal beds.
