摘要
恒晋煤业E9102 工作面临近南山向斜,受向斜影响,工作面上覆含水层水局部富集,预计回采时主要会受顶板上覆含水层及导水断层构造的影响.通过采取井下超前物探探测、钻探探查验证疏放水、合理布置排水系统、地面引流等一系列综合防治水措施,有效保障了工作面安全回采,同时缓解了采区排水压力,节约了排水费用,取得了一定的经济效益和社会效益.
Abstract
The E9102 working face of Hengjin Coal Industry is near Nanshan syncline.Due to the influence of the syncline,the water in the overlying aquifer on the working face is locally enriched.The mining is expected to be mainly affected by the overlying aquifer on the roof and the structure of water conducting faults.Through a series of comprehensive water prevention and control measures such as advanced geophysical detection,drilling exploration to verify drainage,reasonable layout of drainage system,and surface drainage,the safe recovery of the working face is effectively guaranteed,while alleviating the drainage pressure in the mining area and saving drainage costs,achieving certain economic and social benefits.
