| 摘 要： | 以淮南新集煤矿区为例，通过系统采集、分析土壤样品，研究该区煤电工业固废（煤矸石和粉煤灰）堆积对矿区土壤造成的重金属污染。研究结果表明：尽管研究区只有十余年开采历史，煤矸石和粉煤灰长期风化、淋溶已导致其处置堆周边土壤中重金属累积性污染；不同重金属元素在研究区土壤中累积表现出差异性，但均未超过国家土壤二级污染标准，这说明煤电工业固废中重金属向周围土壤迁移是一个缓慢过程。 |
| 关 键 词： | 煤矸石 粉煤灰 污染 土壤 重金属 |

| Abstract: | The pollution of heavy metals from Coal - Power Industrial Solid Wastes （coal mining spoils and Flying ash） piled in diggings soil in Xinji Mine area of Huainan was studied, by collecting and anlysising soil samples . The result shows that the contribution of heavy metals in soil was mainly caused by the weathering and leaching of Coal - Power Industrial Solid Wastes（coal mining spoils and flying ash） and the soil near heaps were polluted and the content of its metals was also accumulated, although this section has been exploited for more than decades. The difference of long - term accumulation and mobility of individual metal was clearly illustrated the difference of their accumulation and transference. The content of all metals were lower than the second Environmental Protection Agency of China. It means that the mobility of heavy metals from Spoils transferring to soil is a slow procedure. |
