萨拉乌苏组含水层对杭来湾井田煤层开采影响性分析

Analysis on Aquifer in Sala Wusu Group Affected to Seam Mining in Hanglaiwan Minefield

论文介绍了杭来湾井田内萨拉乌苏组含水层赋存特征,并利用经验公式计算了3号煤层导水裂隙带,通过数值模拟方法,对萨拉乌苏组含水层流场及水位变化情况进行了预测,结果表明,3号煤层导水裂隙带可能沟通萨拉乌苏组含水层区域,为煤矿防治水工作提供了理论依据。

The paper introduced deposition features of aquifer in Sala Wusu Group of Hanglaiwan Minefield. An empirical formula was applied to calculate a water flow cracking zone of No. 3 seam. A numerical simulation method was applied to the prediction on flow field of the aquifer in Sala Wusu Group. The results showed that the water flow cracking zone of No.3 seam might connect with the aquifer area in Sala Wusu Group and could provide a theoretical basis to the mine water prevention and control.
