Mechanical mechanism of overlying strata breaking and development of fractured zone during close-distance coal seam group mining
This study mainly investigates the mechanical mechanism of overlying strata breaking and the development of fractured zones during close-distance coal seam group mining in the Gaojialiang coal mine. First, a mechanical model for the second “activation” of broken overlying strata is established, and...
