我国煤矸石山综合治理现状及零碳治理探索

Comprehensive treatment status and zero carbon treatment exploration of coal gangue hill in China

在煤炭资源的开采过程中产出大量煤矸石,粉煤灰等副产品,这些副产品大量堆积引发了一系列次生灾害与环境问题。为解决煤矸石山因堆积产生的一系列灾害,基于国内重要矿区矸石山分布情况,分析其主要灾害,研究其治理经验与成果,探索生态处治煤矸石山坡面稳定的方法,探讨了现存煤矸石山治理的不足之处。结合国内外煤矸石利用与绿色治理新技术,提出1种桩-草协同护坡的零碳治理方式,可为我国煤矸石山资源化利用和生态环境保护提供参考。

In the process of mining coal resources,a large amount of coal gangue,fly ash and other by-products are produced,which cause a series of secondary disasters and environmental problems.In order to solve a series of disasters caused by the accumulation of coal gangue hills,based on the distribution of coal gangue hills in important mining areas in China,the main disasters were analyzed,the treatment experiences and results were studied,the ecological treatment methods for the stability of coal gangue hills were explored,and the shortcomings of the existing treatment of coal gangue hills were discussed.It combined with the new technology of coal gangue utilization and green treatment at home and abroad,a zero-carbon treatment method of pile-soil collaborative slope protection is proposed,which can provide reference for the resource utilization and ecological environment protection of coal gangue hills in China.
