摘　　要：岩溶陷落柱作为一种隐伏构造对煤矿高效采掘和安全生产具有显著的负面影响。文章以霍西煤田新良友井田陷落柱为研究对象,查明了陷落柱的发育特征,并提出了注浆加固治理方案。研究结果表明,研究区陷落柱呈现弱胶结和破碎性特征,容易冒顶和诱发滞后导水。对掘进巷道的X11-19陷落柱采用注浆措施,使用水泥浆、双浆液和混合浆液的间接性注入方式,加固顶底板承压能力。注浆加固陷落柱提高了巷道过陷落柱的整体效率,获得了良好的试验效果。Karst collapse column as a hidden structure has a significant negative impact on efficient mining and safe production.This paper takes Xinliangyou well-field system collapse column in Huoxi coalfield as the research object,finds out the development characteristics of the collapse column,and puts forward the grouting reinforcement treatment plan.The results show that the subsided columns in the study area are characterized by weak cementation and fragmentation,easy to fall and induce hysteretic water conduction.The X11-19 collapse column of driving roadway is injected with cement slurry,double grout and mixed grout indirectly to strengthen the bearing capacity of roof and floor.Grouting reinf orcement of collapse column improves the overall efficiency of the roadway through the collapse column,and obtains good test results.
