TECHNOLOGY AND ORGANIZATION OF ROADWAYS DRIVING AND MAINTENANCE IN NEW COAL UNITS OF PJSC «POKROVSKE MINE ADMINISTRATION»

Abstract

Purpose To analyze production experience, scientific and technical developments and assess the prospects for introducing new and improving proven technologies for conducting and maintaining mine workings and improving the organization of these processes. Methods. The methods used were the analysis of the accumulated production experience in the conduct and maintenance of mine workings, the organization of relevant work in Ukraine and the world, scientific and technical literature, and data from surveys and monitoring of the state of the facilities. Findings. The current technologies for conducting capital and excavation workings using the shearer and drilling and blasting methods, methods and means of ensuring the stability of workings during sinking and operation, namely, support systems, additional measures to maintain mining facilities and structures, are considered. The capabilities of the enterprise itself and contractors in terms of use, in particular, in the construction of new coal blocks at Pokrovske Mine Administration PJSC, are assess. The possibility of applying previously known but undeservedly forgotten low-cost additional measures to maintain the stability of the near-contour massif and support structures was substantiate. These opportunities will be realize in the course of the reconstruction of the coal industry after the victory over the aggressor. Originality. The results of the analysis of technologies for conducting and maintaining capital and sectional mine workings, accumulated production experience and scientific and technical developments, organization of relevant work on new coal blocks of Pokrovske Mine Administration PJSC were summarize. Practical implication. The survey and observation of the state of mine workings of new coal blocks based on domestic and foreign production experience were carry out, the level of organization of the relevant types of work was assessed, and recommendations for further development were given in view of the future development of the coal industry.
