摘要
施工巷道在掘进过程中经常遇断层等地质构造,顶板易出现破碎、冒顶现象,加大了支护难度,降低了掘进效率。针对这种施工难题,西山煤电集团屯兰矿在施工12501顺槽巷时通过技术研究,对巷道顶板高冒区采取人工假顶+注浆联合支护方式,取得显著成效。
In the roadway construction process,it is often to encounter faults and other geological structure,theroof is prone to break and fall,increased support difficulty,reduce tunneling efficiency.Aiming at the constructionproblems,by technical research,Xishan Coal Electricity Group Tunlan Coal Mine in construction12501entry adoptartificial roof+grouting combined support method to pass the roadway high roof caving zone,the practice hasachieved remarkable results.
