Movement laws of overlying strata and prevention measures of dynamic disasters under deep adjacent coal seam group with high gas
The repeated mining of deep adjacent coal seam group with high gas has great influence on strata behaviours and dynamic disasters in underground mining. In this paper, the movement of overlying strata and gas for bi-level mining are studied, and then the effective methods of prevention and control d...
