位于峰峰矿区内的羊角铺水源地日开采奥陶系岩溶地下水达为9万m3,为一个大型的水源地。参照《饮用水水源保护区划分技术规范》大型水源地保护区范围确定应采用数值模型模拟计算的规定要求,本文根据羊角铺水源所在地下水系统的水文地质特征,结合模型技术的要求,利用目前国际上流行的visual modflow软件,采用数值模拟法对地下水系统的溶质运移进行模拟预测,并据之确定出羊角铺水源地不同级别的保护区范围,具体是:以水源地地下水开采井为中心,溶质质点迁移100天的距离为半径所圈定的范围作为水源地一级保护区范围,溶质质点迁移1000天的距离为半径所圈定且除去一级保护区以外的范围为二级保护区,将水源地所在的岩溶水子系统的奥陶系灰岩裸露补给区范围划定为准保护区范围。
Yangjiaopu protective district located in Fengfeng mining site is a large water source district.About 90 thousand m3 of karst water from Ordovician is explored in Yangjiaopu every day.Sub-divisional Technological Regulation for Source Protective Zones of Drinking Water(HJ/T338-200) published by State Environmental Protection Administration in 2007 states that division of the large scale water protective zone should use numerical model to simulate and calculate.According this regulation,this paper simulate a...
