China’s coal gangue emissions are very large; long-term storage occupies land and pollutes the en-vironment. Coal gangue belongs to porous media structure, and a series of seepage mechanics problems will be involved in its comprehensive utilization. This paper summarizes and discusses the related seepage mechanics problems in the process of coal gangue utilization, and summarizes its research status and progress, in order to deepen the understanding of the related seepage mechanics problems in the process of coal gangue utilization.
