摘要

陈四楼煤矿2801工作面通过钻孔注浆封堵煤层底板导水裂隙,注浆充填底板太原组上段灰岩含水层,把含水层改造为隔水层或弱含水层,增加有效隔水层厚度,增强抗压强度,切断太原组中、上段灰岩含水层与煤层之间的水力联系,防止煤层底板突水,保证工作面安全回采。
        The 2801 working face of Chensilou Coal Mine uses drilling grouting to deal with plugging water fractured coal floor. And grouting filling floor of Taiyuan group limestone aquifer transformed the aquifer, water-resisting layer or weak aquifer, which increase the effective thickness of water-resisting layer, increase the compressive strength,cut off the section of the connection between the coal seam and limestone aquifer, water-inrush from coal floor, and ensure safety mining face.
