程庄煤矿15305回风巷掘进支护分析

Excavation and Support of 15305 Return Air Roadway in Chengzhuang Coal Mine

在煤矿掘进过程中,及时对巷道进行支护非常重要。根据程庄煤矿的地质情况,对15305回风巷掘进过程中的支护进行了设计。重点分析了巷道支护的施工情况和巷道的矿压观测,以期为巷道的掘进支护提供一定的参考。

In the process of coal mine excavation,it is very important to support the roadway in time.According to the geological conditions of Chengzhuang Coal Mine,the support in the excavation process of 15305 return air roadway was designed,and the construction of roadway support and mine pressure observation of roadway were emphatically analyzed,in order to provide some reference for roadway excavation support.
