Abstract: With the example of underground mine of Sadon lead-and-zinc integrated plant of dolomitic quarry, the researchers proved eco-economic efficiency of combining of their possibilities. The researchers researched economic repercussions of utilization of nonconforming dolomite for production of solidifying mixtures based on mill tailings of polymetallic ores after processing in activators differentially and with integration for each participant. It has been proven that usage of mining waste allows to increase completeness of subsurface use and brings profit depending on completeness and scope of mastering of technologies.
