厂坝铅锌矿位于秦岭山系西南的陇南山区,为特大型铅锌矿山。该矿区弃渣量大,水土流失危害严重。为此,在该矿区原有水土保持治理的基础上,提出了以工程措施为主的综合防治体系,对控制人为新增水土流失效果明显。各项措施实施后,综合治理措施面积达572.45 hm2,工程措施拦渣量2279.34万m3,减少弃渣流失量 2563.47万t,植被恢复率37％,综合减沙效益达到95％以上。
Changba lead-zinc mine is located in the Qinling Mountains in southwestern Longnan Mountain, a large lead-zinc mine. The amount of spoil in the mining area is large and soil erosion is seriously endangered. Therefore, on the basis of the original soil and water conservation management in this mining area, a comprehensive prevention and control system based on engineering measures is proposed, and the effect of adding water and soil loss to the controller is obvious. After the implementation of various measures, the integrated control measures cover an area of 572.45 hm2, and the project measures slag removal amount of 22,793,400 m3, 25,634,700 tons of slag loss reduction, vegetation recovery rate of 37% and comprehensive sediment reduction benefit of over 95%.
