虎峰煤矿穿越上覆采空区巷道掘进技术研究

摘要

Through using design of water detection and water release and gas drainage, improvement of working procedure of roadway excavation and design of roadway support, the author put forward the technology of traversing No.2 level overlaying gob the first coal face and recycling No.2 level remaining resources, which was worth promoting its application.%通过采用探放水设计、瓦斯抽放设计、巷道掘进工艺工序改进、巷道支护设计等方法，成功穿越了2号层上覆采空区圈出首采面，回收了2号层剩余资源,值得推广应用。
