摘要
以新庄孜矿为例,针对覆土造地过程中,煤矸石充填可能带来的重金属元素的迁移污染作了相关分析。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,填埋矸石有利于保护环境,防止环境污染,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。
A case study of land reclamation from Xinzhuangzi coal mine is used to analyze the probability of heavy metal's pollution when coal gangue is used to fill the subsidence area, After reclamation, the floor space of coal gangue dump will be reduced, and subsidence area is reclaimed as cropland. At the same time, coal gangue is buried in the underground, which can play a role in controlling and preventing environmental pollution. It will obtain economic, social and ecological benefits. The model for reclamation in the subsidence area in Xinzhuangzi coal mine sets a good example for other mine areas in Huainan mining area.
