摘要
马路坪矿深部红页岩巷道开挖后在没有支护的情况下,围岩以垂直位移为主,采用新型可伸缩式砂浆锚杆和底角锚杆支护后,有效地抑制了红页岩巷道的水平位移量和垂直位移量,解决了该矿红页岩深部巷道的片帮及冒顶问题。
Abstract
Surrounding rock mass of deep red shale tunnel in Maluping mine were mostly vertical displacement after excavation under the condition of no support.Horizontal displacement and vertical displacement of red shale tunnel were suppressed effectively after adopted new extension type grouted rock bolt and base angle bolting.Rib spalling and roof caving problems of red shale deep tunnel of this mine were solved.
