摘要
运用金川比较成熟的围岩稳定性分析法,结合巷道围岩现场工程地质调查,对1 098 m分段围岩进行了分类。并以此为基础,针对1 098 m分段目前的巷道支护型式,应用巷道收敛变形监测的成果信息,进行了巷道稳定性评价。分析探讨了一次支护、二次支护以及其它支护类型的支护时机问题,为二矿区深部巷道的支护技术研究提供了有价值的借鉴。
Based on stability analysis methods and site survey in Jinchuan,the surrounding rocks on 1 098 m level are classified. According to present support pattern and convergence monitoring result of the roadway,the stability of roadway is evaluated. The analysis is made on the best operation time for the first supporting,second supporting and other types of supporting used for for deep roadway of deposit 2.
