Abstract:
The article details the concept of improving the underground mining of complex structure metal deposits by using systems filling mined-out spaces with solid mixtures. The purpose of the study is to generalize the experience of intensive ore mining while preserving the earth’s surface, as an indicator of the environmentally correct development technology. The research methodology includes observation in full-scale and laboratory conditions, comparison with analogues, experiment, analysis of results, engineering forecasting, semi-industrial and industrial implementation, and theoretical experimentation using standard and new methods. The results of the study. The study highlights the correlation between the performance of ore-bearing stress-deformed rocks, stability of natural and artificial massifs and mine workings. It was determined that structural heterogeneities account for the discrepancy between stresses in massifs and the geostatic distribution law and a mathematical-analytical model for consolidation of discrete rocks was used in the studies. The article shows that voltage regulation makes it possible to use less expensive technologies to reclaim the mined –out space. The study assesses the possibility of using mill tailings, heap leaching, hydrometallurgy, mine waters, ash from electrofilters and wastewater from CHP plants as part of hardening mixtures. The research also considers the issues of environmental safety. The results of the study can be used in modernization of the existing and design of a new mining production.
