Efficient reclamation of available raw material in cemented backfill production

The urgency of the problem of providing mining enterprises with raw materials for the preparation of hardening filling mixtures during underground mining of ore mineral deposits with filling up the worked out space is explained by the desire to increase the range of this environmental protection technology. The aim of the work in the affected direction is to detail the concept of use and efficiency of use of mining waste and related production as components of filling mixtures. The analysis determines the role of hardening filling mixtures based on locally available minerals in managing the state of ore-bearing massifs. A criterion for the environmental and economic efficiency of mining technologies is formulated as the ability to save the earth’s surface from destruction when extracting the rock mass from the bowels. Methods for managing the state of ore-bearing massifs are formulated. Information is given on the ranking of hardening mixtures by strength depending on the functions performed. The characteristic of metal extraction technology by mechanochemical activation in a disintegrator is given. A scheme is given for increasing the activity of the components of hardening mixtures in filling complexes. Economic — mathematical models and nomograms are recommended to determine the efficiency of utilization of substandard raw materials in the manufacture of hardening mixtures. When developing deposits using the underground method for managing the ore-bearing mass by laying the mined-out area with hardening mixtures, it may be economically and environmentally sound to use substandard components of hardening mixtures from locally available cheap minerals.
