榆神矿区强松散含水层下采煤隔水岩组特性的研究

榆神矿区萨拉乌苏组为强松散含水层，但底部发育有一层黄、红土层，根据对萨拉乌苏组强松散含水层底部土层和基岩风化带的分布、性质、水文地质等特征分析，认为该土层与基岩风化带一起构成隔水岩组，因此合理利用其岩组的隔水特性开采煤层，对保护浅部的萨拉乌苏组含水层及防止矿井地质灾害具有重要意义。

Research on Coal Mining under Competent Loose Aquifer and Properties of Aquiclude in Yushen Mining Area

Salawusu formation of Yushen mining area is competent loose aquifer, a aquiclude of loess and laterite in the bottom, and together with bedrock weathering zone showing good water-resisting function. Based on the distribution, character, hydrogeology and so forth features of soil layer and bedrock weathering zone in the bottom of competent loose aquifer of Salawusu formation, hold that existence of soil layer and bedrock weathering zone make coal mining can not destroy to the aquifer of shallow part in Salawusu formation, thereby reach to the purposes of preserve water in coal mining and protect environment.
