摘要
针对Ⅱ614工作面的水文地质特点和生产情况,经过方案对比,选择了优化疏水降压的防治水方案。围绕这一方案,以物探和条件分析法确定了工作面薄弱区,以力学分析法确定了最佳放水点,以给定的时间和排水能力确定了最佳放水量,在确保疏降效果的基础上确定了最佳放水方法。该研究成果在本矿和刘桥一矿得到了推广应用,取得了预期的效果。
According to the hydrogeolodical condition of working face Ⅱ614, mining activities and design cooperation, the water discharge method was selected. Cooperating this procedure, the weak areas of coal floor were detected by geophysics, the optimum discharge sites were determined through mechanical analysis, the suitable water flowage and discharge operation were obtained according to given time and pumping capacity. The achievement have been successfully applied to water hazard control in the working face with similar hydrogeology conditions both in in the Fiest Liuqiao Coalmine and The Second Liuqiao Coalmine.
