摘要
通过对刘桥矿区主要含水层的环境同位素测试分析 ,表明研究区内各含水层δ18O值为 - 5 .5 1‰～- 10 .87‰ ,平均 - 9.34‰ ;δD值为 - 5 6 .3‰～ 83.4‰ ,平均 - 71.4 8‰ ,且δD与δ18O值自浅到深依次降低。还分析了该矿区地表水、新生界松散层一含水和二含水、煤系砂岩水、太灰水、奥灰水氢氧稳定同位素一般特征 ,研究了矿区主要含水层水的补给环境及奥灰水与其他含水层之间的联系。
The environmental isotopes in the major aquifer of Liuqiao coal mining area have been tested and analyzed.The values of δ 18O of the aquifer are between -5.51‰ ～-10.87‰,average value is -9.34‰,and the values of δD of the aquifer are between -56.3 ‰～ -83.4‰,average value is -71.48‰.The values of the δD and δ 18O decrease with the decrease of depth.The general characteristics of the surface water,the first aquifer and second aquifer of the Quarternary,the coalaquifer,the Taiyuan Formation limestone aquifer and the Ordovician limestone aquifer in the mining district are analyzed.The supply and runoff condition and the relation between the Ordovician limestone aquifer and other aquifers in the area are studied.
