摘要
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 ,对新桥硫铁矿坑下岩体结构进行调查与质量评价 ,根据调查结果将顶板岩层划分为三个等级 ,对矿山安全生产有重要指导作用 。
After structure investigation and quality evaluation, three levels roof masses are determined by both CSIR and Q classification methods according to their physical mechanical properties, structural features, rock quality data (RQD) and hydro geologic conditions in Xinqiao Pyrite Mine, which is important to its stooping operation and can be used for reference by other related mines.
