The Relationship Between the Manifestations of Rock Pressure and the Relative Deformation of Surrounding Rocks

摘要

On the basis of analysis of the manifestations of the rock pressure in domestic and abroad practice the authors have the aim to research above named manifestations in conditions of new coal deposits of Kuzbass (Erunakovskoe, Kazankovskoe etc.) and to form the normative document for mining in these conditions. Presents the results of the displacement contour of the benchmarks on the conveyor and ventilation drifts during the testing of the 34 layer on the “Tagaryshskaya” mine. The formed system of measuring points and applicable instruments is described. The relative deformation of the coal mass on the conveyor drift at the approach of the coal face is given. Thus, the relationship of the displacements and relative deformations with the manifestation of rock pressure is attempted by the authors.
