丹巴燕子沟金矿开发对区域水环境的影响

四川丹巴燕子沟金矿位于川西高原,地处大渡河上游的自然保护区,生态环境脆弱。通过对区域地表水和地下水的环境质量评价,分析了矿山开发对区域水环境的影响。根据水文地质条件,从环境保护角度,对四川丹巴燕子沟金矿开发提出了防污建议,如矿硐的底部应和硐口外的废石堆场设集水沟渠,加强尾矿库的管理,定期监测矿山地表水和地下水的的水量和水质等,以利于资源和环境的可持续发展。

Influence of the Exploitation of Yanzigou Gold Mine on Regional Water Environment in Danba

Yanzigou gold  mine in Danba is located in western Sichuan plateau and the up stream of nature reserve area of Dadu River，where the ecological environment is very vulnerable.Through evaluating the quality of surface-water and groundwater，the influence of minerals exploitation on the regional water environment are analyzed.According to the condition of hydrogeology，some countermeasures for pollution in exploitation of Danba Yanzigou gold mine in Sichuan are proposed from the angle of environmental protection，which include of building a catch-water ditch between the wasted-rock yard outside of tunnel and its bottom，strengthening the management of tailings dam，and regularly monitoring the quantity and quality of surface and groundwater，etc..This can facilitate the sustainable development of resources and environment.
