摘要
煤矿条件复杂,在超高巷道开口掘进时采用传统的施工方法会严重制约掘进速度,不但需要过高的劳动及支护成本,而且很难排除一些难以预料的危险因素。通过大同煤矿集团塔山煤矿的掘进实践,提出了煤矿复杂条件下超高巷道开口掘进的施工工艺和支护方法。
For the mining conditions are complicated in Tashan coal mine,the traditional driving method of opening excavation technology for super-high roadway reduced the driving speed,increased supporting cost and had unexpected risk factors. By the driving practice in Tashan coal mine of Datong Coal Mine Group,the construction technology and supporting method of opening excavation technology for super-high roadway under complex conditions was proposed.
