Complex mineral mining leads to critical earth's surface disturbance and environmental pollution from industrial waste. This research aims to comprehensively study, assess and show the current scale of the earth's surface disturbances in the largest mining region of Ukraine -the Kryvyi Rih Iron-ore Basin and suggests ways to improve the situation. based on backfill technologies for the earth's surface rehabilitation and industrial waste utilization. It has been determined that the contribution of the Kryvyi Rih Iron-ore Basin to waste generation is 92.08% of the total volume of waste accumulations in Dnipropetrovsk Oblast and 65.5% in Ukraine as a whole, amounting to 10.7 billion tons. It is determined that 65.25% of the total disturbed land area is industrial waste, 34.76%quarry cavities and mine failure zones, occupying 49% of the Kryvyi Rih city area. An analysis of waste accumulation density in allotted areas shows that per 1 m 2 of land area, on average, 183.5 tons of dump waste rocks and 73.5 tons of beneficiation tailings are placed. Disposal of beneficiation tailings is recognized as a priority, because their utilization is slower, occupy the largest area, creating a risk of dams breaching and intense dusting from tailings dams surface, threatening the environment and public health. For the first time in Ukraine, a concept for the earth's surface rehabilitation for various industrial purposes has been developed based on paste backfill technologies. Paste backfill technology implementation is prioritized in the central and northern parts of the city, which can dispose of at least 65-70 million tons of waste in cavities and reclaim about 200 hectares of land. The research results are valuable for the development of strategies or programs to overcome the technogenic-ecological crisis in the city. The rehabilitated earth's surface can be usefully involved in various infrastructure projects for the development of the industrial and economic potential of an industrial city such as Kryvyi Rih.
