Study on evolution law of water-conducting fracture zone in steeply inclined coal seam longwall fully-mechanized top-coal caving face

Meikuang Anquan
To study the development height of the water-conducting fracture zone (WCFZ) in the steeply inclined longwall fully-mechanized top-coal caving face, the 202 fully-mechanized caving face in the west No.2 mining area of Wangjiashan Coal Mine was taken as ...
