Abstract: In order to carry out ecological restoration and treatment of abandoned mines，from the perspective of comprehensive utilization of industrial solid waste，it is proposed to use industrial solid waste for ecological backfill of abandoned mines. Taking the treatment of an abandoned mine in Huoqiu County，Anhui Province as an example，based on the principle of combining comprehensive utilization of solid waste with mine restoration and treatment，the ecological backfilling process of abandoned mines， backfilling and pollution control requirements，current situation investigation of abandoned mines，proper‐ ty investigation of solid waste，and backfilling project of abandoned mines were analyzed，and the ecologi‐ cal backfilling way of abandoned mines was determined. The analysis and research show that the tailings in Huoqiu County can be ecologically backfilled to realize the effective utilization of the abandoned mine vol‐ ume of about 49.362 m2 . After ecological backfill，it can be reclaimed into forest land，which can realize the reuse of land resources.
