摘　　要：不连沟煤矿浅埋深巨厚煤层且层理发育,遇到构造时顶板及两帮破碎严重,围岩难以控制。通过采用W型钢带改变围岩表面受力分布,缩小锚索间距,提高围岩支护刚度,有效控制了围岩,顺利通过构造区。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.
