Abstract:
The purpose of the article is to detail the concept of humanization of ore extraction technologies in the underground mining of metal deposits. The main problem of mining has become the handling of processing waste, the amount of which is increasing due to the transfer of ore reserves to the inactive category due to selective extraction of ores from the subsoil. The methodology of the problem research includes experiments, modeling, theoretical analysis and generalization of practice data. The stages of development of mining production in the historical section are given. Information is provided on the possibilities of traditional enrichment technologies for the disclosure of ores and the loss of ore components in tailings. The role of the phenomenon of controlling the state of the massif in the process of purification extraction and reducing the dilution of ores by rocks during the development of critical stresses is explained. An algorithm for controlling the state of the array using the geomechanical effect is proposed. It is shown that the volume of diluting rocks depends on the phenomenon of the formation of a rigid hinge arch from wedged rocks. The options for correcting the state of the massif due to overlaps, inclination of the ore walls, creation of a protective wall and anchoring of rocks are presented. A variant of development with the integration of technologies at the stages of existence is recommended. The characteristic of technologies with the leaching of metals from ores is given, as the main reserve for increasing the mineral resource base for obtaining metals due to the involvement in the production of substandard ore reserves for traditional technologies. A forecast of ore mining conditions in the future has been made. It is concluded that a radical measure to reduce the risk of waste is the use of combined chemical enrichment and mechanical activation during their disposal.
