摘  要:以新庄孜矿为例,针对覆土造地过程中,对煤矸石充填可能带来的重金属元素的迁移污染做了相关分析,结果表明矿区重金属污染程度不强,工程区地下水质达到Ⅲ类以上.施工过程中采用煤矸石与土的多层结构充填模式,提高了矸石保熵性.采用煤矸石充填塌陷区,既减少矸石山占地面积,又能在塌陷区覆土造地,同时有利于保护环境,具有较大的经济效益、社会效益和环境效益,对淮南矿区覆土造地及工农业持续发展具有重要的示范意义.Probability of of heavy metal pollution resulted from coal gangue filling in covering soil reclamation in Xinzhuangzi coal mine was analyzed. The results show that such pollution is not serious and groundwater quality reaches the third class in the mining area. The filling mode of multi-layer structure of coal gangue and soil was adopted which improved the entropy preservation of coal gangue. After the reclamation, the area occupied by coal gangue dump was reduced, making the subsidence area become cropland. In addition, it is favorable for environment protection, resulting in a great economic profit and social effect. Therefore, this reclamation model in the subsidence area of Xinzhuangzi coal mine is a good example for other mine areas in Huainan mining area.
