Abstract
The substantiation of environmental and resource-saving technologies for the repayment of voids in underground ore mining is provided, which ensures the preservation of the day surface and the vital activity of the population living in the influence zone of the mining region. The expediency of utilizing mining and metallurgical production wastes into underground mined spaces (man-made voids) as components of hardening filling mixtures is shown. The effectiveness of the use of vibration, mechanical and electrical activation of components of the hardening filling mixture in mining enterprises has been established. The research results can be used in underground mining of ore deposits of complex structure.
