Studies conducted in the mines «Rostovugol», showed that, for assessing the sustainability of preparatory excavations in the management of sewage treatment works is enough to determine the allowable values of convergence of the roof and ground-level workings and potential energy of elastic deformation of the pillars. These indicators can be used in the coal mines of other basins.
Abstract: It is suggested the method for the determination of interentry pillars in mining the seams prone to rock bursts. The width of pillars is determined depending on the seam thickness and depth of mining operations.
