根据岩层物理力学性质、岩体结构和构造、岩体质量指标RQD、水文地质条件等因素 ,采用CSIR分类法、Q系统分类法 ,将新桥硫铁矿顶板岩层划分为三个安全等级 ,对矿山安全生产有重要指导作用 ,可为其它矿山提供借鉴
According to physical and mechanical properties of rock strata, structure and structure of rock mass, rock mass quality index RQD, hydrogeological conditions and so on, CSIR classification method and Q system classification method are used to divide the roof strata of Xinqiao Pyrite Mine into three safety classes. Mine safety production has an important guiding role, can provide reference for other mines
