摘　　要：掌握锑矿开采活动影响下的水文地球化学特征,厘清污染特征及污染来源,对矿山开采活动背景下地下水污染防治与修复具有重要意义。为探明贵州大厂锑矿水环境状况,在地表水和地下水野外取样的基础上,利用水化学分析和同位素测试手段,分析了矿区水化学特征及类型,并研究了矿山酸性水硫酸盐、硫氧稳定同位素的组成特征,分析了污染来源及其污染路径。结果表明:研究区地表水的主要污染指标为Mn、Hg、Sb、SO_(4)^(2-),地下水的主要污染指标为Mn、Sb、Al、Hg,水环境受污染情况严峻;根据硫端元分析,水环境主要污染源来自废渣堆淋滤水和平硐排水。研究结果可为矿区锑污染的长期动态监测、矿业开发活动和生态环境保护提供参考。It is of great significance to understand the hydrogeochemical characteristics and clarify the pollution characteristics and sources under the influence of antimony mining activities for the prevention and treatment of groundwater pollution under the background of mining activities.In order to find out the water environment of Dachang antimony mine in Guizhou Province,based on the field sampling of surface water and groundwater,the hydrochemical analysis and isotopic testing methods were used to analyze the characteristics and types of water chemistry in the mine area,study the composition characteristics of sulfate and oxygen and sulfur isotopes in the mine acidic water,and analyze the pollution sources and the migration and transformation law of antimony in the water environment.The results show that the main pollutants in the surface water are Mn,Hg,Sb,SO_(4)^(2-),and the main pollutants in the groundwater are Mn,Sb,Al,Hg.The water environment is seriously polluted.According to the analysis of sulfur end element,the main pollution source of water environment comes from the leaching water of waste slag pile and the drainage of adit.The research results provide an important reference for long-term dynamic monitoring of antimony pollution in soil and water,mining development activities and ecological environmental protection.
