Assessment of Rigid Overlying Strata Failure in Face Mining

The method of overlying strata failure assessment of extracted seams is based upon the simultaneous assessment of surface subsidence and seismic activity, considering the spatial-temporal progress of mining, depending on the character of the rock mass.The rigid overlying strata failure assessment re...
