| 摘 要： | 112201工作面是梅花井煤矿首采工作面,位于矿井南端浅部,切眼靠近鸳鸯湖背斜轴部。工作面涌水量从2009年4月份开始回采时的15m3/h,增至2010年3月份的230m3/h。工作面的突然涌水导致大量淋水,从而使采区底板严重泥化,给矿井安全生产带来巨大威胁。分析认为,工作面的主要充水水源为2-1煤的顶板含水层（七里镇砂岩）,主要通道为顶板的采动裂隙带。通过实施探放水和疏放水工程,工作面下隅角的涌水量由180m3/h降至30m3/h以内,极大的减少了含水层突然涌水对工作面的危害,为梅花井乃至鸳鸯湖矿区防治水工作起到了积极作用。

| Abstract: | The No.112201 working face is initial working face in the shallow south end of the Meihuajing coalmine,its open-off cut close with the Yuanyanghu anticline axis.The water inflow was increased from 15m3/h during April 2009 at the start of winning to 230m3/h in March 2010.Large amount dripping water caused by the inflow has made serious winning district coal floor rock degradation and threatening coalmine production safety.The analysis considered that the main water filling source is from No.2-1 coal roof aqu... |
