Abstract:
Through introducing the wall rock and anchor network coupling support technology, the basic characteristics of achieving coupling support in deep compound roof seam is rest with the coupling of deflection, intensity, rigidity and structure. According to the monitoring results of 200 m at Wu
9-21210 airway in No.10 coal mine of Pingmei Shares which uses the wall rock and anchor network coupling support technology,roof of roadway,both sides and floor heave are normal. These makes roadway for a time into a lane.
