摘要
漳村煤矿2203瓦排巷在受毗邻刚刚结采的2202工作面的动压影响下,采用让压锚杆支护达到了较好的效果,满足了巷道瓦斯排放的需要,为采动影响下小煤柱巷道支护提出了新的方案。
Under the influence of adjacent 2202 dynamic pressure face, Zhangcun Coal Mine 2203 gas emission drift adopt pressure bolt to achieve better results and meet the needs of roadway gas emissions, which proposed new program for the mining small coal pillar drift.
