THE MODERN STATE OF CAPITAL MOUNTAIN MAKING AND SUGGESTION IS IN RELATION TO SUPPORT AND INCREASE OF THEIR FIRMNESS ON PJSC «SHU «POKROVSKE»

Abstract

Purpose. Development and ground of rational parameters and energyeffective technologies of realization, method of guard and support of making are with the increase of depth of bedding. Methods. Further study of conformities to law of deformation of containing heterogeneous pedigree array and exposure of conformities to law of dynamics of the tensely-deformed state of containing array of making at the use of new methods of support or well-known with the changed parameters in certain geological terms on the basis of visual inspection and instrumental measuring of the mountain making at not in one’s dreams mountain pressure; comparative estimation of possible methods of support of making. Results. The improvement of the technology of installation and construction of the anchor-metal arch fastening when using the bearing capacity of the contour massif, taking into account its strengthening and unloading, is substantiated. Scientific novelty. Improvement of the design and technology of installation of anchor-metal arch fastening is based, in terms of the involvement of technical solutions, on increasing and using the bearing capacity of the near-contour massif, taking into account its unloading, based on modern research and many years of experience of PJSC “SHU “Pokrovske”. Practical significance. Achieving high rates of construction of capital and preparatory mining works, which ensure the highest production of coal in Ukraine. Keywords: mining, near-contour massif, methods of supporting mining, mining and geological conditions, anchor metal arch fastening.
