AN ALTERNATIVE TECHNOLOGY OF ORE EXCAVATION IN CONTACT WITH THE FILLING MASS

The authors propose a new resource-saving technology for extraction of ore deposited in contact with the filling mass. This technology enables better extraction of the mineral, reduces ore dilution with the backfilling material, improves profitability of the mineral resource industry, while ensuring safe working conditions. The authors recognize as the most effective one the scheme of ore extraction in contact with the filling mass by means of forming ductile filling masses with a strengthened layer along its contact with the mineral.
