煤矿区水环境特征研究——以柳林泉域西部某矿区为例

Study on water environment characteristics of a mining area-Take a mining area in western Liulin spring area as an example

为了解柳林泉域西部某矿区地下水的运动规律,本文采用了环境同位素示踪法对该矿区水样中的^(18)O、D、T含量特征进行分析研究。研究表明:1)研究区地下水的矿化度在平面上均具有明显规律;2)研究区各含水层的地下水循环条件差异明显:地下水径流条件好的地段,矿化度明显降低,地下水滞流区的矿化度明显升高;3)奥灰含水层13个水样同位素分析表明,研究区奥灰含水层地下水循环条件不佳,属滞留区。

In order to understand the movement of groundwater in a mining area in the west of Liulin spring region,the tracer method of environmental isotopes is used in this paper to analyze the content characteristics of ^(18)O,D and T in the water quality samples of this mining area.The research results show that:1)The salinity of groundwater in the study area has obvious rules in plane;2)There are obvious differences in groundwater circulation conditions among aquifers in the study area:the salinity decreases significantly in the area with good groundwater runoff conditions,while the salinity increases significantly in the groundwater stagnant area;3)Isotope analysis of 13 water samples from ordovician limestone aquifer shows that the groundwater circulation condition of ordovician limestone aquifer in the study area is not good,and it is a retention area.
