Overburden Strata Synchronous Breaking and Dynamic Load Mine Pressure Mechanism of Cross-Ditch Mining in Close-Distance Coal Seams

Repeated mining of shallow-buried close-distance coal seams can disturb the fractured strata remaining in the goaf of the upper coal seam. Under gully terrain, mining disturbance is coupled with surface-relief effects, which may reactivate the overburden structure and induce dynamic strata-pressure behavior. In particu...
