大断面煤巷快速掘进支护技术研究

Research on the rapid excavation support technology of large section coal roadway

本文以011603工作面回风顺槽大断面煤巷为工程背景,对影响煤巷快速掘进因素进行分析,并相应地提出了煤巷快速掘进优化施工方案,通过工业性试验,在有效提高煤巷掘进速度的同时,有效维护了巷道围岩稳定性。

Based on the return air along the trough of 011603 face big cross section coal lane as the engineering background, factors affecting the speedy drivage in coal roadway is analyzed, and accordingly put forward the rapid drivage in coal roadway, optimization of construction scheme, through industrial test, at the same time, improve the speed of excavating in coal roadway, effectively maintain the stability of surrounding rock of roadway.
