TECHNOLOGY OF COMBINED EXCA VA TION OF THIN ORE VEINS FROM MASSES PACKED BY STRONG ROCKS
The article proposes a technology that includes advanced mechanical highly selective mining of thin ore veins and mineralized host rocks by means of a mining shearer and subsequent explosive loosening of the waste rock mass to form the required cross-section. The combined equipment of the mining shearer, which provides cutting with diamond discs of cracks in solid rocks with a relatively high productivity, as well as the subsequent shearing off of pillars of rocks limited by cracks, will significantly reduce the energy consumption of the extraction of valuable mineral raw materials. Drilling and blasting operations after mechanical extraction of minerals will provide high productivity of loose rock loosening. The implementation of the technology will allow preserving the natural quality of minerals extracted from the bowels and reducing the cost of its subsequent processing
