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

Abstract

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.
