摘要
煤矿井下动压显现强烈,复合顶板的回采巷道围岩变形严重,有冒顶的潜在风险。为解决强动压影响条件下复合顶板巷道的围岩控制问题,以2329工作面为研究对象,通过优化支护方案,加强顶板和两帮巷道围岩的支护强度,对复合顶板围岩变形起到了较好的控制作用,经现场实践验证,该改进方案具有良好的适用性。
The dynamic pressure in the deep part of the coal mine is strong,and the surrounding rock of the mining roadway with composite roof is severely deformed,with a potential risk of roof collapse.In order to solve the problem of surrounding rock control in strong dynamic pressure composite roof roadways,this paper took 2329 working face as the research object.By optimizing the support plan,increasing the support strength of the roof and two sides of the roadway surrounding rock,it had played a good control role in the deformation of the composite roof surrounding rock.After on-site practice verification,this improved plan has good applicability.
