利用水化学场、温度场判断矿坑水补给源及其比例

DETERMINAION OF RECHARGE SOURCES OF PIT WATER AND PROPORTION WITH THE AID OF HYDROCHEMICAL AND HYDROTHERMAL FIELDS

不同补给源的水,其水质、水温存在差异。根据质量和热量守恒原理,通过对不同补给水源进行长期观察,可确定矿坑水的补给源及其比例。作者推导出了存在二种和三种补给水源情况下各补给水源所占比例的计算公式,并应用到湖南洞口县的石下江煤矿,取得了良好效果。

There are differences in chemical constituents and temperature among water from different recharge sources. According to the conservation principle of mass and heat, through long-term observation of the water in different recharge sources, the sources and proportion of pit water can be determined. The authors have derived the formula for calculation of the proportion of the water from each recharge source in the cases when two or three recharge sources existed, and it is applied to Shixiajiang coal mine in Dongkou, Hunan, and good result is achieved.
