针对马脊梁矿一盘区3煤工作面在采掘过程中出现的涌水现象，结合矿井实际情况以及工作面顶板覆岩和水文地质特征，对8117工作面进行富水性分区，并制定了工作面采掘及回采期间顶板疏放水技术方案。结果表明，顶板含水层的疏放水总量为503.8 万m3，动态补给量为357.27 m3/h，疏放残余水量为296.5 m3/h，达到了预期效果，含水层静储量得到了有效疏放，保障了工作面安全回采。

In view of the water inflow phenomenon in the mining and excavating process of No.3 coal working face in No.1 panel of Majiliang Mine, combined with the actual situation of the mine and the characteristics of roof overburden and hydrogeology of the working face, the water abundance zoning of the No.8117 Face was carried out, and the technical scheme of roof draining water during mining and excavating of the working face was formulated. The results showed that the total amount of water drainage in the roof aquifer was 5.038 million m3, the dynamic recharge was 357.27 m3 / h, and the residual water drainage was 296.5 m3 / h, which achieved the expected effect. The static reserves of the aquifer were effectively drained to ensure the safe mining of the working face.
