Abstract
In order to solve the difficult problem of soft rock governance in Qingshuiying Coal Mine and achieve normal mining and excavation continuity,by analyzing the main problems existing in support,a fully enclosed pressure bearing ring soft rock governance direction of"strong support,top fixation,and floor governance"is proposed.The composite support way of"basic support of high-strength pres-tressed anchor cables with full cross-section+strengthened support of anchor cable truss+shotcrete enclosed+full length anchoring+reverse bottom arch governance of bottom bulge"is adopted for construction,which improves the single entry level and achieves support safety,provide reference for the control of soft rock roadways with similar surrounding rock conditions.关键词
