摘　　要：煤矿矸石山中包含大量的固体废弃物,对矿区环境产生污染,破坏生态环境。而固体废弃物处理能够通过环境治理与生态修复实现,可以促进煤矿矸石山生态环境的可持续发展。为了提高煤矿矸石山的环境治理与生态修复效果,减少煤矿矸石山中固体废弃物的环境污染,提出了煤矿矸石山环境治理及生态修复技术研究。以S煤矿为研究对象,根据研究区内降雨状况和植被生长情况,以造林结构、密度和时间为基础,建造了林地,通过绿化造林的方式,制定了煤矿矸石山环境治理方案,测试了煤矿矸石山的生态修复效果。结果表明,通过绿化造林,不仅可以有效降低煤矿矸石山近地层空气中的SO2、NOx和粉尘含量,对矸石山的空气起到了净化的作用,还可以降低土壤和水体中微量元素和有毒元素的含量,具有较好的修复效果,降低煤矿矸石山中固体废弃物对环境的影响。There are a lot of solid wastes in the coal gangue, which pollute the environment of the mining area and destroy the ecological environment.The solid waste treatment can be realized through environmental treatment and ecological restoration, which can promote the sustainable development of the ecological environment of coal mine gangue hill.In order to improve the effect of environmental treatment and ecological restoration of coal mine gangue hill and reduce the environmental pollution of solid waste in coal mine gangue hill, research on environmental treatment and ecological restoration technology of coal mine gangue mountain was proposed.Taking S Coal Mine as the research object, according to the rainfall and vegetation growth in the research area, based on the afforestation structure, density and time, the forest land was built.Through afforestation, the environmental treatment plan of coal mine gangue hill was formulated, and the ecological restoration effect of coal mine gangue hill was tested.The results showed that afforestation can not only effectively reduce the content of SO2,NOxand dust in the air near the ground layer of the coal mine gangue hill, but also purify the air of the gangue hill.It can also reduce the content of trace elements and toxic elements in the soil and water, which has a good repair effect and reduces the impact of solid wastes in the coal mine gangue hill on the environment.
