| 摘 要： | 针对五沟矿井田内"三隔"、"四含"沉积特征和含隔水性进行分析,得出"三隔"层(组)粘土类可塑性好,膨胀性强,厚度大,分布稳定,隔水性良好,是区域及煤矿内重要的隔水层(组);"四含"直接覆盖在煤系地层之上,是矿坑充水主要补给水源,但其"岩性"泥质含量高,渗透性差,补给条件较差,一般富水性弱。

| Abstract: | Within Wugou Coal Mine "3rd seperating","4th aquifers " sedimentary characteristics and water bearing properties are analysed,and obtaines that the "3rd aquifuges"(group) clay soil in the region and the coal mine is an important confining(group),which plasticity is well,expansion is strong,thickness is big,the distribution is stability,water separating character is good;" 4th aquifers " was directly covered above the coal formation stratum,which is the main supply water source of mine,but because its "lithological character" is high argillaceous,permeability is badl,the supply condition is worse,and general aqueous is weak. |
