摘　　要：由于梅花井煤矿112202工作面距2-1煤顶板粗砂岩含水层距离较近,含水层厚度局部增大,在回采过程中受采动影响,将使工作面沟通顶板含水层,导致工作面涌水量加大,影响工作面正常回采,因此采取预疏放治理,效果总体较好,基本达到了预期疏放目标,大大降低了采后采空区的涌水量,对保证工作面安全、高效回采起到了重要作用。The roof of №12202 mining face is coarse sandstone aquifer of Zhiluo Formation. Because the sandstone aquifer is close to the mining face,the diversion fissure zone would connect aquifer due to the seam mining and influence the normal production of mining face. By taking the drainage measures,the water inflow of mined-out area was decreased significantly,and safety and high efficient production was guaranteed.
