Due to super high seam located at shallow mining depth and bedding development, Buliangou Coal Mine’s ceiling plate and side wall cracked seriously. Surrounding rock is hard to control. After applied Wshape steel trip to change surrounding rock surface stress distribution, and shorten anchor cable interval, support rigidity was increased. Tectonic region was successfully passed.
