山西省阳城县上孔煤矿地质灾害预测分析及防治研究

Study on prediction and prevention of geological disaster in Shangkong Coal Mine of Yangcheng County,Shanxi Province

阳城县上孔煤矿拟开采3、9、15号煤层,在开发利用过程中,为了改善矿山地质灾害的防治效果,采用矿区地表移动变形预测模型,预测地表移动变形。通过矿山采空区地质环境综合预测,预计地表最大下沉量6883.54 mm,并将其地质灾害影响程度预测评估分为“严重区”和“较轻区”。“严重区”影响范围43.97 hm^(2),“较轻区”影响范围515.25 hm^(2)。通过矿山地质灾害预测分析,提高地质灾害的监测预警工作,并加强地质灾害防治工程,保护人民生命、财产损失,达到防灾减灾的目的。

No.3,9 and 15 coal seams are planned to be mined in Shangkong Coal Mine of Yangcheng County.In the process of development and utilization,in order to improve the prevention and control effect of mine geological disasters,the surface movement and deformation prediction model of the mining area is adopted to predict the surface movement and deformation.Through the comprehensive prediction of the geological environment of the mine goaf,the maximum surface subsidence is estimated to be 6883.54 mm,and the prediction and evaluation of the impact degree of geological disasters is divided into"serious area"and"light area".The influence range of"serious area"is 43.97 hm^(2),and that of"light area"is 515.25 hm^(2).Through prediction and analysis of mine geological disasters,to improve monitoring and early warning of geological disasters,strengthen geological disaster prevention and control projects,to protect people′s lives and property losses,and to achieve the purpose of disaster prevention and reduction.
