摘要
北京市金矿主要分布在北山地区,在怀柔、平谷、密云及昌平等区县,赋矿地层主要为长城系沉积岩、四合堂群变质岩。金矿选冶工艺主要是混汞—氰化工艺及浮选工艺。为了解北京市矿山生产对国土资源的影响状况,保护和改善矿山及周边地区生态环境,减缓矿山生产对环境的影响程度,介绍了北京市金矿分布、地质背景对环境的影响,说明了污染源三废排放量、排放强度,矿山生产对大气环境、水环境、土壤环境、生物环境的影响,及矿山生产次生地质灾害、地形地貌破坏等。并提出金矿山环境影响的防治对策,为政府治理、整顿矿山环境及发展矿业提供基础数据及建议。
The main distribution of gold deposits in Beijing is located in Beishan area,mainly in Huairou,Pinggu,Miyun and Changping district. The mineralization strata are mainly the metamorphic rocks of the Great Wall series sedimentary rock and the quadrate. The metallurgical process is mainly mixed mercury-cyanide process and flotation process. This article briefly illustrates the distribution of gold deposits in Beijing,shows the geological background of environmental impact,the pollution of "three wastes"emissions,emissions intensity,mine production of atmospheric environment,water environment,soil environment,biological environment,the influence of secondary geological disasters and mine production,landform destruction,etc. The countermeasures against the environmental impact of gold mine were put forward. To understand the status of the mine production of Beijing's influence on the land and resources,ecological environment protection and improvement of the mine and surrounding areas,slow down the degree of impact on the environment of mine production,governance,consolidation and development of the mining mine environment for the government to provide basic data and suggestions,have very important reference significance.
