摘要
煤矸石具有资源、能源、污染、经济等多重属性,因各区域内组分差异大,煤矸石综合利用方式也各不相同。煤矸石大宗利用具有成本低、处理量大的特点,但针对特殊需求和煤质,应分质分级处理,每个阶段都有其不同的利用途径。根据区域内煤矸石化学性质,可探索梯级利用途径,充分发掘煤矸石的资源价值和经济效益,发展低碳经济。本文论述煤矸石带来的问题,然后结合煤矸石的化学性质,分析其资源化利用途径,以提高资源综合利用率,消除环境风险,实现经济发展和环境保护的双赢。
Coal gangue has multiple attributes such as resources,energy,pollution,and economy,due to the significant differences in composition within each region,the comprehensive utilization methods of coal gangue also vary.The largescale utilization of coal gangue has the characteristics of low cost and large processing capacity,but for special needs and coal quality,it should be classified and treated according to quality,and each stage has its own different utilization ways.Based on the chemical properties of coal gangue in the region,cascade utilization ways can be explored to fully explore the resource value and economic benefits of coal gangue,and develop a low-carbon economy.This paper discusses the problems caused by coal gangue,and then analyzes its resource utilization ways based on its chemical properties,in order to improve the comprehensive utilization rate of resources,eliminate environmental risks,and achieve a win-win situation of economic development and environmental protection.
