The substantiation of environmental and resource-saving technologies and technical means for the processing and disposal of man-made formations and waste from mining and metallurgical production into underground mined-out spaces (man-made voids) as components of hardening filling mixtures is given. This will ensure the safety of the day surface from destruction and the vital activity of the population living in the zone of influence of the mining region. It was found that for the mines of the State Enterprise "VostGOK" (Ukraine), the utilization rate of waste of own production for the hardening filling is from 0.45 to 0.68; hydraulic – from 0.56 to 0.75; free-flowing – 0.62, and the extraction of each ton of salable ore is accompanied by the output of 0.7–0.8 tons of waste. The research results can be used in underground mining of ore deposits of complex structure and mining and metallurgical production.
