贵州省晴隆-安龙金矿矿山环境污染调查分析

贵州省黔西南州晴隆-安龙地区主要贵州"红土型"金矿的主要产区,也是贵州省湿法炼金的主要生产基地,区内金矿生产在一定程度上促进了当地乃至贵州省经济社会的发展,同时也对当地矿山生态环境造成了较大影响,产生很多环境地质问题,矿山矿渣、废渣等产生的环境地质问题尤为突出。为了解该地区矿山有害废物种类、含量变化范围和污染程度及分布,通过对调查区42件矿渣、废渣所含As、Sb、Hg及73件浸出液中As、Sb、Hg、CN-、S2-有害元素分析,确定晴隆、兴仁、安龙各调查区存在的主要的有害元素及污染程度,根据综合污染指数(GTi)划分出中度、轻度污染区域,提出今后该区矿山地质环境恢复治理建议和有待研究的环境地质问题。

Investigation and Analysis of Environment Pollution in Qinglong-Anlong Gold Mine in Guizhou Province, China

Qinglong-Anlong region is the main produce area of lateritic gold deposit and major production base for liquid alchemy in Guizhou Province, China. The mine production promoted local and even the whole province''s economy to some extent, but also damaged the mine environment. More geo-environmentalproblems could be brought in mine by mine slag. In order to know the type,content, pollution degree, distribution of harmful waste material in mine slag and residue of survey area in Qinglong, Xingren and Anlong Counties, based on the test result of As, Sb and Hg in slag and As, Sb, Hg, CN^- and S^2- in leaching solution, survey area was divided into different zones with different pollution states according to the comprehensive pollution index. Environmental and geological problems to be solved and suggestions on restoration and treatment of gold mines in this area were also posed.
