Abstract: Coal gangue is a kind of significant byproduct during coal mining and coal preparation processes. Due to the lack of effective comprehensive utilization methods, a large amount of coal gangue cannot be effectively utilized and can only be stored on-site, especially in the northwest region of China. The storage on-site occupies lots of land resources, and also causes severe environmental pollution and ecological damage. Therefore, it is crucial to explore and establish a comprehensive utilization technology system for coal gangue, as well as to improve the corresponding technical standards system. This paper analyzes the production and utilization of coal gangue in China over the past decade and investigates the current domestic technology and standard systems for the comprehensive utilization of coal gangue, which summarizes the existing problems that hinder the comprehensive utilization technology system for coal gangue in China. These problems include the inability to satisfy large-scale disposal demands, the lack of support from a technical standards system and the significant regional technological characteristics. To address the current deficiencies of technical specifications and standards during the technology promotion process, this paper summarizes the current status of standards in the field of comprehensive utilization of coal gangue and identifies the problems within the existing standard system, which include the absence of a pollution prevention and control standards system, as well as the lack of comprehensive utilization technology specifications. This paper offers corresponding suggestions for the coal gangue comprehensive utilization industry. The objective is to provide reference and guidance for the development direction of the technology system and the improvement of the standard system for the comprehensive utilization of coal gangue, ultimately achieving a more efficient, safe, and environmental friendly utilization of coal gangue.
