Research progress on technologies for the resourceful utilisation of coal gangue to produce soil
摘要
Abstract
As the largest volume of solid waste generated during coal mining and washing,the long-term stockpiling of coal gangue has led to issues such as land occupation,environmental pollution and geological hazards,which have become key bottlenecks constraining the green and low-carbon development of the coal industry.Traditional methods of coal gangue disposal and resource recovery suffer from shortcomings such as limited disposal capacity,high energy consumption and low ecological value-added.In contrast,the production of artificial soil from coal gangue offers mul-tiple advantages,including large-scale disposal,ecological restoration,arable land substitution and low-carbon e-missions reduction,making it a vital technological direction for the coordinated development of solid waste resource recovery and land reclamation in mining areas.This paper systematically reviews the strengths and weaknesses of con-ventional coal gangue disposal and resource recovery technologies,elucidating the core advantages of coal gangue-based soil in terms of process,disposal capacity and ecological benefits;it summarizes the preparation methods and technical characteristics of coal gangue-based soil from the perspectives of pre-treatment and core preparation proces-ses;It analyses the physicochemical and ecological properties of coal gangue-based soil,its application scenarios,and combined physical,chemical and biological maturation and improvement techniques to address its shortcomings.Finally,it identifies current issues such as the lack of standards,unclear long-term risks and lengthy maturation cy-cles,and outlines future development directions for efficient production,risk management,standardization and large-scale application.The aim is to provide theoretical guidance and technical support for the high-value,eco-friendly utilization of coal gangue and the ecological restoration of mining areas.关键词
