Paleychuk M. Substantiation of stopes stability parameters of horizontal workings in intensity fracturing rocks in deep mines

The objective of the work is substantiation of stopes stability parameters of horizontal seam's workings in intensity fracturing rocks in deep coal mines. Research methods: a review and synthesis of scientific and technical literature, collection and analysis of geological surveying data on mountain workings, a study of strength properties of rocks, mine instrumental measurements, numerical study of deflected mode of coal and rocks massif, statistical processing of experimental data. Results: regularities of development of indicators of stability of workings from speed of growth fissures in rocks roof of anthratcitic seams, the algorithm of calculation of deflection angle from the vertical, the prevailing stress on the support by the rocks of the roof, is the cross-sectional shape of the horizontal workings of deep coal mines under intensive asymmetric displacements of the rocks.Calculation methodology lop of stopes stability parameters of horizontal seam workings under emergence of fissures and movement of breeds of roof that have a skewed relative to the vertical direction. New methodology is passed for the use to PAO "LuganskGIPROSHAKHT" and SE "UkrNIIPROEKT". Scope (industry) used in the mining industry at rebuilding and construction of workings, in scientific research and design establishments of mining areas in educational institutions.
