此专利提出了防止岩体发生冲击地压的方法,此法包括确定巷道工作面附近的岩体应力和巷道边界以外形成卸荷槽。这种方法的特点是:通过减弱岩体受力状态的途径,以提高对冲击地压的防护效果,要确定在巷道周围受采掘工作影响形成的裂隙带,并在 This patent proposes a method of preventing rock mass from being subjected to rock burst. This method includes determining rock mass stress near the working face of the tunnel and forming a relief groove outside the boundary of the tunnel. This method is characterized by: by weakening the way of the rock mass stress state, in order to improve the protective effect of rock burst, it is necessary to determine the fracture zone formed by the excavation work around the roadway and at
