Abstract
The main scientific and practical results of studies on increasing the environmental safety of mining production are made on the basis of the utilization of mining waste and processing of ore raw materials in the filling of underground waste areas, storing tailings with the addition of hardening agent based on solidification of hazardous ingredients, determining the formulations of hardening mixtures, assessing their strength and reducing the risk for environment by transferring them to a solid state. The analysis of known technologies and technical means for managing specified storage parameters, laboratory and production experiments, physical modeling and selection of the compositions of hardening mixtures, analytical studies, comparative analysis of theoretical and practical results are given. The results of the experience in the use of hardening mixtures and the methods for studying the hardening of MSP tails and the evaluation of their strength are described. Recommended new technologies for the preparation of hardening mixtures for the immobilization of tailings when filling out the tailings.
