| Abstract: | In view of the problems of Tangyang Coal Mine-410 belt roadway,which is affected by faults,needs to pass through the soft rock stratum of Shihezi Formation,the rock is soft and broken,easy to be powdered when encountering water,the bolt can not reach the pre tightening force,and can not guarantee the safety of roof support,the composite support of anchor net and concrete-filled steel tube support is adopted to achieve the design support effect and avoid the repeated repair of the roadway. |
