松散破碎膨胀型软岩巷道支护技术研究

Study on Support Technology of Unconsolidated Fragment Soft Rock Drift

以盛源矿业公司牛西井软岩巷道为研究对象,首先分析了巷道支护面临的复杂地质条件与围岩破坏情况,然后进行了软岩巷道破坏机理分析,进而考虑软岩巷道的支护特点与支护原则,确定了软岩巷道支护方案与支护参数,最后对软岩巷道支护效果进行了数值模拟分析,验证了支护方案与支护参数的合理性,从而为类似条件的软岩巷道支护提供了参考依据。

This paper based on Shengyuan Mining Co. Niuxijin soft rock drift, analyzed the complexes geology condition to support. Then analyzed the wreck mechanism and the support feature in soft rock drift, decide the support precept and parameter. At last it analyzed the support effect. Validate the support precept and parameter with reason. So it offered some reference to the similar soft rock drift.
