摘要
大冶铁矿尖林山采场在开采过程中出现了巷道垮冒、围岩不稳等现象,采场安全受到影响。从内因和外因2个方面讨论了巷道失稳的原因,从改变回采方式、改善采场结构参数和加强支护3个方面阐述了提高采场稳定性的措施,保证了矿区安全。
In Jianlinshan Stope of Daye Iron Mine, some unsafe factors like as roof fall and unstable surrounding rock were appeared in the mining process. In order to maintain the security of the mine, some reasonable support and reinforcement methods were used. Based on the discussion of surrounding rock failure, the support methods are optimized, which ensures the roadway and rock stability.
