5环境影响评价5.1煤炭生产对环境的影响煤炭生产对环境的影响主要是煤矸石、煤矿瓦斯和矿井水排放,以及采煤引起的地表沉陷。东部(含东北)地区。人口稠密、土地资源稀缺,大多数煤矿位于平原地区,主要环境影响是地表沉陷。2015年,东部(含东北)地区产生煤矸石和煤泥1.27亿t、矿井水10.24亿m3、
5 Environmental Impact Assessment 5.1 Environmental Impact of Coal Production The environmental impact of coal production is mainly coal gangue, coal gas and mine water discharge, and surface subsidence caused by coal mining. Eastern (including northeast) area. With dense population and scarce land resources, most coal mines are located in the plains. The main environmental impact is surface subsidence. In 2015, 122 million tons of coal gangue and coal slime were generated in the eastern (including northeast) region, 1.024 billion m3 of mine water,
