| 摘 要： | 深井巷道围岩随着开采深度的增加其稳定性也发生了变化。通过对深井巷道围岩稳定性的分析,认为影响深井巷道围岩稳定性的3个主要因素是围岩性质、采深和支承压力,得到了根据围岩性质、采深和支撑压力来控制巷道稳定性的结论。

| Abstract: | With the increase of mining depth,the host rock stability has changed.In this paper,the stability of host rock in deep mine tunnel is analysed.It is thought that the main factors of influencing the stability of host rock in deep mine are rock properties,the depth of mine and the support pressure.The conclusion is we must control the stability of host rock based on the rock properties,the depth of mine and the support pressure. |
