Technology of Fully-mechanized Top Coal Caving Face Passing Through Mine Abandoned Roadway in Chengzhuang Coal Mine

Meikuang Anquan, 2020
For the characteristics of the two empty lanes which are parallel empty roadways in front of 3311 fully mechanized caving face in Chengzhuang Mine and empty roadway in roof, and the problems that overhanging support pressure overlaps, the mine pressure appears severely and the roof collapses, etc, filling empty lane is a reasonable way to pass empty ...
