沙溪铜矿地下水动态特征研究

Study on Dynamic Characteristics of Groundwater in Shaxi Copper Mine

本文对沙溪铜矿的水质和地质进行了实地检测和分析,主要从三个方面研究了地下水的动态特征,这三个方面分别是矿区地下水的水位动态、水化学成分分析、地下水的渗流场。实验的结果表明,地下水的动态属于气候——开采型,地下水需要大自然不断的补给,而补给来源就是大气的降水。地下水分为很多层次,其中深层的地下水只能接收少部分的补给水,这就造成了水头逐渐降低的结果。地表水和地下水之间几乎没有联系。另外,作者建议要加强矿区的水文地质的相关管理工作,完善管理和监督系统,建立一个全方位的地下水监测系统,且系统运用一系列先进技术成为了动态管理系统。

In this paper,the water geology and geology of Shaxi Copper Mine are tested and analyzed on the spot.The dynamic characteristics of groundwater are mainly studied from three aspects:the dynamic state of groundwater level,the analysis of water chemical composition and the seepage field of groundwater in Shaxi Copper Mine.The experimental results show that the groundwater dynamics belong to the climate-exploitation type,and the groundwater needs the continuous recharge of nature,and the recharge source is the precipitation of the atmosphere.Groundwater is divided into many layers,in which the deep groundwater receives only a small part of the recharge water,which results in the gradual reduction of water head.There is little connection between surface water and groundwater.In addition,the author suggests that we should strengthen the related management of hydrogeology in mining areas,improve the management and supervision system,establish a comprehensive groundwater monitoring system,and the system uses a series of advanced technologies to become a dynamic management system.
