摘要
为保证塔山扩区三盘区2301巷道安全顺利过破碎带,施工永久支护后,采取架设密集工字钢棚、注射填充剂的方法加固顶板,不仅加快巷道掘进速度,而且降低了事故率,取得了显著的效益。
The paper introduces the optimization measures of reinforcing the support injecting filling agent, which can fasten the driving speed with low accident rate and zone. roof by laying intensive I-steel beam and remarkable benefit in crossing the fracture
