摘要
平朔井工三矿9煤赋存条件差、地质构造较多,掌握9煤巷道围岩地质力学参数是实现本煤层巷道锚杆支护可靠性及合理性的基础,基于此,对井工三矿9煤巷道围岩地质力学参数进行原位测试及分析,为井工三矿9煤巷道支护设计提供技术保障。
No.9 coal seam in No.3 mine of Pingshuo Mine has poor occurrence conditions and many geological structures.Mastering the geomechanical parameters of surrounding rock of No.9 coal seam roadway is the basis for realizing the reliability and rationality of roadway bolt support in this coal seam.In this paper,the geomechanical parameters of surrounding rock of 9 coal roadway in Jinggong No.3 mine are tested and analyzed in-situ,so as to provide technical guarantee for the support design of 9 coal roadway in Jinggong No.3 mine.
