Abstract
Liangjia Coal Mine is a typical soft rock, after the excavation of tunnel , the surrounding rock stable period is short, apparent stress is fast, using simple bolt mesh shotcrete support, the support strength is a serious shortage for service cycle relatively long roadway, the use of the rigid flexible multiple combined support that the roadway support effect is ideal, the safety guarantee, and save the costs of labor and material, has great reference value and promotion value for the similar conditions for roadway support .关键词
