煤矸石山是煤炭开采和加工过程中的必然产物,它含有炭质可燃物和黄铁矿,长期堆放,黄铁矿会自燃,向空气中排放SO2、CO2、CO、H2S等有害气体,严重污染大气、土地。造林绿化是解决煤矸石污染的唯一有效途径,基于此,对山西煤矸石山堆积地的造林模式和造林技术分别做了详细总结、论述,其对矿区的造林生产具有一定的指导意义。
Coal gangue hill is an inevitable product in the process of coal mining and processing. It contains carbonaceous combustibles and pyrite. When it is stored for a long time, pyrite spontaneously ignites and emits harmful gases such as SO2, CO2, CO and H2S into the air. Pollution of the atmosphere, land. Afforestation is the only effective way to solve the pollution of coal gangue. Based on this, a detailed summary and discussion of afforestation mode and afforestation technology of coal gangue pile accumulation in Shanxi are provided, which are of guiding significance to the afforestation and production of mining area.
