Research on groundwater pollution barrier of acid reservoir in copper mine

Abstract

The waste rock produced by mining in Copper mine has high sulfur content, which leads to the risk of acidic water pollution to the downstream groundwater and soil environment. Based on the pollution prevention and control ideas of source control and process control, the groundwater barrier project of vertical and horizontal seepage prevention is implemented for acid reservoirs. Through the comparison of groundwater monitoring data from upstream and downstream of the vertical barrier, it is found that the acid pollution of the water in the downstream of the barrier is significantly improved compared with upstream of the barrier, and the concentration of heavy metals and other characteristic pollutants is significantly reduced.
