Abstract
Affected by the cross mining, a mine II 13 return air rise that adopted in the U29 type steel support, and the roadway maintenance extremely difficult. The reasons for the failure of U type steel support are analyzed, and the high strength reinforcement support with high strength anchor mesh cable is determined. Numerical simulation analysis shows that, high-strength bolt mesh cable support added the support strengthen of the weak parts which has help for the obvious improvement of the moment distribution in the top position, the industrial test results show that the roadway reinforcement effect is good, the surrounding rock of roadway deformation effectively control.关键词
