Abstract

Based on the analysis of studies in domestic and abroad practice it is defined that the accumulated experience is a subject to significant adjustment in conditions of new Kuzbass coal deposits (Erunakovskoe, Kazankovskoe and others.). There is a comparison between the obtained measurements of the manifestation of rock pressure, obtained by the following methods: measuring the displacements of contour and depth benchmarks, pressure in the hydrostatic supports of the mechanized complex, relative deformations of the coal massif on the conveyor drift are shown at the approach of the coalface during the development of the seam. The relation of different cases is presented. Also the distinctive feature of rock pressure formation in comparison with the same picture observed at other deposits remains in the process of rapid blanking of the waste area disintegrated into the pieces of small size mudstones, which are being used as the cushion. In the final part, the solutions for investigating the manifestations of rock pressure in neighboring mines of new deposits are proposed.
