新生界松散含水层抽水试验止水方法的研究——以祁东煤矿南部采区水文地质探查工程为例

两淮煤田绝大部分是被厚数百米的新生界松散层掩盖,其中含有若干个含水层,为掌握这些含水层的富水性和水文地质特征,需要对含水层进行抽水试验.新生界松散含水层抽水试验止水方法有多种,通过对祁东煤矿南部采区水文地质探查工程SQ9孔新生界底部“四含”抽水试验止水方法的研究,提出了一种简便而有效的止水方法.

Study on the Pumping Test Sealing Method in the Cenozoic Loose Aquifer

Two Huai coal largely covered by hundreds of meters thick Cenozoic loose bed,which contains a plurality of aquifer,to master water and hydrogeological features in these aquifer,the groundwater pumping test is necessary.Cenozoic loose aquifer pumping test sealing methods are various,through studying on SQ9 Kong Xinsheng bound bottom" four contain" pumping test sealing method of the hydrogeological exploration engineering in Southern of Qidong coal mining area,the article puts forward a kind of simple and effective sealing method.
