摘要
针对鹤壁九矿3103下底板抽放巷外段掘进期间揭露的陷落柱,通过钻探取心工作来确定该陷落柱的范围、地质及水文地质的分布情况以及含水、导水特征,根据分析结果采取合理的防治水措施,以井下底板注浆加固为主,对该陷落柱进行底板注浆加固治理,综合评价对该陷落柱的研究治理效果,为下一步采区工作面的布置提供可靠的技术资料依据,为矿井及企业的防治水工作提供新的技术支持。
For the collapsed column exposed during the excavation of the outer section of the 3103 lower floor extraction roadway in No.9 Coal Mine of Hebi Coal Industry,the scope of the collapsed column,the distribution of geology and hydrogeology,and the characteristics of water content and water conduction were determined by drilling and coring.Reasonable water prevention and control measures are mainly based on the grouting reinforcement of the underground floor,and the collapsed column is grouted for the reinforcement treatment of the floor,comprehensively evaluates the research and treatment effect of the collapsed column,and provides reliable technical data for the layout of the working face in the next mining area.Provide new technical support for mine and enterprise water control work.
