掘进巷道围岩稳定性分析及控制研究

Study on stability analysis and control of surrounding rock in driving roadway

由于巷道掘进会引起其围岩内应力的释放,围岩发生变形破坏,为保证围岩稳定就需要有效地支护。本文在分析掘进巷道围岩变形破坏机理和不同的地质条件因素对围岩变形破坏的影响基础上,针对巷道围岩条件,提出了采用锚注联合支护技术对掘进巷道围岩进行控制,结果可以为掘进巷道围岩的稳定和支护提供一定的参考。

The roadway excavation will cause the release of the surrounding rock stress; the surrounding rock will deform and fail, so ensuring the stability of surrounding rock need effective support, based on the analysis of tunneling roadway surrounding rock deformation and failure mechanism and the impact of different geological condition factors on the surrounding rock deformation, according to the condition of roadway surrounding rock, bolting and grouting combined support technology is proposed to control roadway surrounding rock, the results can provide certain reference for roadway surrounding rock stability and support.
