摘要
研究区为典型的南方岩溶区,地下岩溶管道十分发育,为了获得其地下水等水位线图,使用GMS软件包,并采用MODFLOW的排水沟渠子程序包以及河流子程序包来模拟管道流。数值计算结果表明,拟建项目的废水入渗到含水层后将向西南方向渗流,最终流入黑水河。尾矿渣的淋溶试验结果显示,由于选矿废水中的重金属含量低,故预计项目建成后选矿废水对含水层的重金属污染风险性很小。
The research area is a typical southern type of karst water system where karst pipes are greatly developed.In order to get accurate contour maps of groundwater table,a GMS software is used to simulate the groundwater flow.During simulation,a ditches package and river subroutine package in MODFLOW are also applied to simulate the turbulent flow in karst pipes. The simulation results show that the waste water will penetrate toward the southwest from the site of the proposed project to Heishui River. However,the contents of heavy metals in leaching water are very low when ferrohydrite tail slag is subjected to leaching tests. This leads to a conclusion that the risk of karst water in research area suffered heavy metal pollution from the proposed project is very small.
