Seepage Analysis and Prevention Technology Research of Wastewater Reservoir in Metal Mine

Based on the investigation of the seepage causes wastewater reservoir of in one metal mine, the erosion mechanism is analyzed that the acid mine drainage erosion the earth-rock dam, and the technology program of vertical anti-seepage wall is chosen that use concrete with coal fly ash as anti-seepage wall. The practice has proven that such concrete vertical anti-seepage wall can improve the impermeability and structure of concrete, enhancing the anti-seepage wall durability under acidic environment. It can be reference to similar projects.
