摘要:

本文主要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。确定了3号煤层导水裂隙带可能沟通的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。

关键词: 萨拉乌苏组, 导水裂隙带, 杭来湾井田

Abstract:

The characteristic of Salawusu Fm in Hang Laiwan area are introduced in detail and the water-conducting height is also given by empirical formulations in this paper. Furthermore, the flow characteristics and water level changes of Salawusu Fm aquifer are predicted by numerical simulations. Finally, a conclusion is reached that the water-conducting may be high enough to reach the Salawusu Fm aquifer, what provides a theoretical basis for prevention and control of the mine water.

Key words: Salawusu Fm, Water-conducting zone, Hang Laiwan area
