The Analysis of Stability of Surrounding Rock in Deep Mine Tunnel

摘要

With the increase of mining depth, the surrounding rock stability has also changed. In this paper, the stability of surrounding rock of deep mine tunnel is analyzed. And it is considered that the three main factors which influence the stability of country rock in deep mine are rock properties, the depth of mine and the abutment pressure. The conclusion is that we must control the stability of country rock based on the rock properties, the depth of mine and the abutment pressure.
