| 摘 要： | 根据氧－１８、氘、氚同位素在邢台煤矿放水试验中的变化规律，分析了奥灰水对大青水的影响程度、大青水的可能来源等，得出井田的３个水文地质单元富水地段以及补给源和补给强度。特别是用环境同位素方法进一步证实了该井田是一个３面阻水、北面进水的断块岩溶水区。为煤矿防治水提供了依据。

| Abstract: | n the water discharge trial in Xingtai coal mine,the variation laws of the environmental isotopesT,D and 18 O in the water are revealed.According to the laws,the degree"Daqing" aquifer affected by Ordovician Karst aquifer and the possible recharge source of"Daqing" aquifer are analysed and discussed,and the minefield can be divided into three hydrogeologic units which are different in the source and the intensity of rechargeOf underground water. The study of the isotopes indicates that this mine field is one of fault block karst waterarea whose north side is the only location that underground water inrushes but the other three sides are difficultfor water inrush.This result will be very imPOrtant to harnessing and preventing mine water in the mine field. |
