| 摘 要： | 利用氢氧稳定同位素(δD、δ18O)和放射性同位素氚(T)分析了金川矿区不同水体间的水力联系,初步判断了井巷排水的主要补给源,研究结果表明:金川矿区井巷排水是深部基岩裂隙水和经过蒸发效应的大气降水混合的产物,不同地段排水中生产水与深部基岩裂隙水比例不同,深部基岩裂隙水比例16%~83%,生产水比例84%~17%;井巷排水主要为上世纪60年代或70年代补给的充填析出水。

| Abstract: | In this paper, stable isotope hydrogen and oxygen and radioisotope tritium were used to analyze
hydraulic relationship among different water bodies in Jinchuan mine, and to preliminarily determine the primary
rechargement to mine drainage. The results indicated that the drainage came from the mixtures of deep bedrock-
fissure water and precipitation water after evaporation effect. The percentages of the production water and the
deep bedrock -fissure water differ in different part, with the former 84% ~17% and the latter 16% ~83% . The
drainage water is mainly the released water filled in the last century 60s'' and 70s''. |
