Granted: 2021-03-15
Abstract: FIELD: mining industry. 
     SUBSTANCE: invention can be used for the development of thin ore veins folded by strong rocks containing valuable mineral raw materials. It's a combined method of disintegration of a rock mass in the development of thin ore veins, including laser action on the rock in the near-surface layer of the processed rock mass, followed by layer-by-layer milling of rocks with a combine. Laser slits are cut along the boundaries of the contacts of a thin ore vein and mineralized host rocks with a gas-liquid jet supplied to the laser treatment zone for cooling and cracking the material. Selective mining of the near-surface layer of a thin ore vein and mineralized host rocks is carried out sequentially. A thin ore vein is mined with a disk cutter within the boundaries of the contacts, and mineralized host rocks with a paired disk cutter are mined outside the boundaries of the contacts to ensure the possibility of deepening the disk cutter with a casing during the subsequent pass. The ore mass of a thin ore vein loosened by a disk cutter is poured into a storage tank, and a rock mass of mineralized enclosing rocks loosened by a paired disk cutter is poured into a container. After working off the near-surface layer to the depth of softening, the combine is returned to its original position along the rails, the telescopic struts of the swing frame are lifted and the combine is re-passed. After the formation of the working to the design depth, drilling of boreholes is carried out, along with their loading and blasting of the boundary massif of mineralized enclosing rocks.  
     EFFECT: combined method provides higher productivity and technological efficiency by increasing functionality, reliability and ensuring the selectivity of the extraction of thin ore veins, reducing dilution, and reducing the environmental load in the mining area.
