As a major solid waste, coal gangue not only occupies land but also pollutes groundwater and air, and even triggers geological disasters. Therefore, comprehensive resource utilization of coal gangue has received increasing attention. This paper analyzes research progress in backfilling treatment, extraction of valuable elements, improvement of agricultural production, development of sound-absorbing and noise-reducing ceramsite, manufacturing of building materials, and subgrade filling. It is proposed that efforts should be intensified in strengthening top-level design, enhancing pretreatment of coal gangue, extending industrial chains, fostering talent cultivation, and improving industrial policies to create an environment for harmless disposal and resource utilization of coal gangue.
