Research on the deep apart bedding rupture engineering soft rock roadway supporting technology

The deep roadway embedding is large, geology conformation is more complex, stress combination effect is evident. The roadway surrounding rock control become a main restrict factor in the safety and high effect production of coal mine. In this paper, by analyzing theroadway’s wall rock property and mechanical environment, based on the influence of wall rock to supporting form and effect, classified the deep wall rocks and afforded the corresponding supporting method. The supporting results indicated that the high intensity "bolt+net+cable+band" combining supporting technology can ensure the apart bedding rupture engineering soft rockroadway’s stability and gain good effect.WT
