摘要
针对雅店矿1417工作面上覆含水层富水通过导水裂隙带增加了工作面采后涌水量,给工作面安全回采造成了影响,为了减少工作面回采后的涌水量,尤其是减少周期性顶板垮落过程中的涌水量,采用井下钻探对工作面顶板含水层进行探放,顶板含水层富水实现“削峰平谷”,使顶板水平稳泄出,保障工作面安全开采。实践证明,严格按照探放水规定对上覆岩层含水层进行探放,是一种减少采后涌水量有效可行的方法。
In order to reduce the gushing water after mining,especially the gushing water in the process of periodic roof collapse,underground drilling was used to explore and release the water-bearing layer on the roof of the working face,and the water-bearing layer on the roof can be cut and leveled off to stabilize the water gushing and ensure the safe mining.Practice proved that,in strict accordance with the provisions of water exploration and release of the overlying rock aquifer to explore and release,was an effective and feasible method to reduce the amount of water gushing after mining.
