为解决潞安王庄煤矿8110超长高瓦斯运输巷掘进速率较低的问题,分析了高瓦斯和掘进工艺对8110运输巷安全快速掘进的影响。基于理论计算得出了瓦斯抽采的必要性,并提出了“边掘边抽瓦斯、优化掘进工艺”的快速掘进技术。
In order to solve the problem of low tunneling rate of 8110 ultra-long high-gas transportation lane in Wangzhuang Coal Mine, the influence of high gas and driving technology on safe and fast heading of 8110 transportation lane was analyzed. Based on the theoretical calculation, the necessity of gas drainage is deduced, and the rapid excavation technology of “boring and edge gas drainage and optimizing excavation technology” is put forward.
