摘要
利用地质力学原位测试法对阳辿煤矿北三采区已掘巷道进行工作巷道围岩物理力学参数信息测试工作,获得测试区域地应力场在量值上属于低应力值区域,在测试区域顶板10m范围内岩体岩性主要为粉砂岩、细砂岩和石灰岩。顶板岩层比较坚硬,岩层整体完整性较好,局存在破碎现象,巷帮围岩结构完整。测试结果将为阳辿煤矿巷道支护设计提供基础数据支撑,通过合理的支护参数,既保证了矿井安全生产又实现了技术及经济效益。
using the method of geomechanics in situ test on the north three Yangchan coal mine mining area has been digging work of roadway surrounding rock physical mechanics parameter information test work,obtain test area ground stress field on the value belongs to the low stress value area,within the scope of the test area roof 10 m rock lithology is mainly for the powder sandstone,fine sandstone and limestone.The roof rock is hard,the rock overall integrity is good,the bureau exists the fracture phenomenon,the roadway two sides surrounding rock structure integrity.The test re-sults will provide the basic data support for the support design of the roadway in yanghan coal mine.Through the reasonable support parameters,it can bring great technical and economic benefits to the mine and escort the safe production of the mine.
