Failure Characteristics and Evolution Law of Overburden Structure Under Repeated Mining of Close‐Distance Coal Seam Group in Ningdong Mining Area

ABSTRACT It is difficult to control the mine pressure in the coal face under the close coal seam group. On the basis of the mining background of 4‐1#, 4‐2#, and 4‐3# coal seams in the I01 mining area of the Ningdong mining area, the fracture characteristics and evolution law of the overburden struct...
