摘　　要：酸性水库作为铜矿区重要的环保设施,现行标准规范对新建酸性水库防渗提出了明确建设和环境管理要求。然而,对于运行已久而存在防渗坝渗漏或通过地下水渗漏等方式对库区及下游环境造成风险可能的酸性水库,目前尚未有明确的防渗治理标准规范。以某铜矿区酸性水库为例,通过分析区域水文地质条件,调查环境风险水平,对水平防渗和垂直防渗进行比选,论述其可行性,确定了“垂直防渗”方案为该酸性水库的治理方案,并提出治理建议,为我国酸性水库同类治理工程提供借鉴参考。As an important environmental protection facility in a copper mining area,current standards and specifications have put forward clear construction and environmental management requirements for seepage prevention of acid reservoirs.However,for acid reservoirs that may cause leakage of anti-seepage dams or risk to the reservoir area and downstream environment through groundwater leakage due to long-term operation,there is no clear standard specification on anti-seepage treatment.An acid reservoir in a copper mining area is taken as an example in this study,by analyzing regional hydrogeological conditions,investigating the level of environmental risk,the feasibility of horizontal seepage control and vertical seepage control is discussed,the"vertical seepage control"scheme is determined as the treatment scheme of the acid reservoir,and the treatment suggestions are put forward.This paper provides a reference for a similar control project of acid reservoirs in China.
