With the deepening of the mining depth of the 3310 working face of the Wangpo Mine, the safety uncertainty in the depth of the mine increased, the degree of shattering of the top plate transportation increased, the rate of sinking and the structural deformation gradually strengthened, the original way of maintaining the top plate in advance of the support method can no longer meet the production requirements of safe mining. In response to this situation, ZQLY4000/20/38 overhead brackets on the 3310 working surface of the mine was adopted, instead of the original top plate support method. The practical application results showed that the new overhead support method with high safety and reliability, which reduced the labor intensity, with good application.
