摘要
煤矸石山是煤炭开采和加工的必然伴生产物,由于其特殊的立地条件和富含大量的重金属污染物,是矿区的重要污染源之一,极易对矿区及其周围环境造成危害。复垦是当前煤矸石山治理和综合利用最为有效的措施,文章从煤矸石山的立地条件特征的分析入手,从植被复垦技术、微生物复垦技术与复垦模式三方面分析和总结了煤矸石山复垦技术取得的研究成果,并针对当前研究中存在的一些亟待解决的问题进行了探讨,以期为煤矸石山复垦技术进一步研究提供参考。
Coal gangue dump is the inevitable product generated from coal mining and processing. It is one of the key pollution sources of mine due to its special site conditions and rich containing of heavy metal pollutants and consequently easily endangers the mine areas and surrounding environment. The previous studies show that reclamation is the most effective measure for management of coal gangue dump. In this paper, the features of site conditions of coal gangue dump are first analyzed. The study results obtained from reclamation of coal gangue dump are also analyzed and summarized from the aspects of vegetation restoration technology, microorganism reclamation technology and reclamation model. Problems existing in the current studies to demand urgent solution are also discussed, providing reference for the further study of reclamation technologies for coal gangue dump.
