Abstract: In order to study the comprehensive treatment and utilization ideas of environmental geological disasters in mining city open-pit mines, the distribution of mining cities across the country have been investigated. The results show that among the three-level mining cities, most of the first-level dependent cities are resource-exhausted cities, and the economic development situation is grim. It is imminent to take comprehensive governance and utilization. Common geological disasters of mining city open-pit mines include collapses, landslides, ground fissures, etc., which have adversely affected the coordinated development of cities and open-pit mines. The development of weak interlayers and the effect of water on rock and soil are the leading factors affecting environmental geological disasters. The treatment of the mine-city open-pit mine should include the open-pit mine interior and the disturbance zone around the open-pit mine. The overall utilization should follow the development ideas of “national support and local leadership”, “treatment of multiple disasters and combination of treatment and use”, “respect for nature and maintenance of landforms”, “renewable resources and recycling”.
