摘要
煤矸石是在煤矿巷道掘进、煤炭开采和洗选过程中产生的伴生矿物.因其未能得到有效利用,常露天堆放于煤矿工业场地周边.大量的煤矸石露天堆放不仅占用土地资源,而且会通过雨水淋溶、自燃等方式对周边生态环境造成污染.对贵州省不同区域煤矸石的组成成分进行调查,针对煤矸石性质浅析了煤矸石发电、提取元素、生产建材和生态修复等综合利用途径的可行性,并提出建议,对促进贵州省煤矸石综合利用、实现煤炭行业绿色高质量发展具有重要意义.
Abstract
Coal gangue is an associated mineral produced in the process of coal mine tunneling,coal mining and washing.Because it is not effectively utilized,it is often piled up in open piles around coal mine industrial sites.A large amount of coal gangue stacked in the open not only occupies land resources,but also causes pollution to the surrounding ecological environment through rainwater leaching,spontaneous combustion and other ways.This paper investigates the composition of coal gangue in different regions of Guizhou Province,analyzes the feasibility of comprehensive utilization pathways such as power generation,extraction of elements,building materials and ecological restoration of coal gangue in view of the nature of coal gangue and puts forward six suggestions.It is of great significance to promote the comprehensive utilization of coal gangue in Guizhou Province and realize the green and high-quality development of coal industry.
