小煤柱沿空掘巷支护控制实践的研究

Research on the Practice of Small Coal Pillar Supporting Control in the Roadway Driving along the Goaf

根据大同煤矿集团同忻煤矿8305工作面5303巷道地质条件,研究了小煤柱沿空掘巷合理支护参数。现场实测结果表明,优化后的支护参数能够满足工作面安全掘进需要,为同类型小煤柱沿空掘巷提供相应的参考。

According to the geological conditions of 5303 roadway in the 8305 working face of Tongxin Coal Mine, Datong Coal Mine Group, the reasonable supporting parameters of the small coal pillar along the air excavation roadway were studied. The field test results show that the optimized support parameters can meet the safety driving requirements of the working face. It can provide corresponding reference for roadway driving along gob with the same type of small pillar.
