华丰煤矿1411巷道(第五段)地面埋深近1000m,巷道倾角较大,并且巷道围岩物理力学特性较差,属于典型的大倾角软岩冲击地压深埋巷道,因此采用合理的巷道支护方式对控制巷道围岩变形非常重要。巷道永久支护采用锚杆(索)、锚带网和复合U型棚联合支护,并通过对现场进行矿压观测,发现巷道变形在预计的范围内,能有效保证1411巷道(第五段)的稳定性和服务年限,对同类深埋巷道支护具有借鉴作用。
Huafeng Coal Mine 1411 roadway (fifth paragraph) ground buried depth of nearly 1000m, large roadway inclination, and roadway rock physical and mechanical properties of poor, belong to a typical deep soft rock rock burst pressure buried roadway, so the use of reasonable roadway Support and control of roadway surrounding rock deformation is very important. Roadway permanent support using bolt (cable), anchor belt mesh and composite U-shaped shed joint support, and by the site of the rock pressure observation found that the deformation of the roadway in the expected range, can effectively ensure the 1411 roadway (fifth paragraph ) The stability and service life of similar support for deep roadway with reference.
