Original language description

The method of evaluation of the firm failure is based on the coincident evaluation of the surface subsidence and the seismic activity due to dynamics configuration in mining in dependence on mine ? geological conditions of extraction. The result of the method is the interpretation of tensile deformations which could cause the failure of the firm roof layers or, on the other hand, a strutting arch was formed over the mined ? out area in which quasi-equilibrium stress state has occurred. Another usable result of the evaluation method is the interpretation of the dimensions of the stope, at which the breakthrough of the firm roof occurred. The method is employable in areas where mining by the method of longwall mining to controlled carving with the minedthickness more than c. 1m. The results of this method are used as the amendment of contemporary known methods of rock burst protection, and this (regarding the use of surface measurements for the evaluation) namely in higher roof areas.
