METHOD FOR SELECTIVE DEVELOPMENT OF COMPLEX STRUCTURE DEPOSITS OF SOLID MINERALS Russian patent published in 2021 - IPC E21C41/00 

FIELD: mining.

SUBSTANCE: invention relates to mining industry and can be used for development of complex-structure deposits, including thin steeply falling veins containing valuable mineral raw material. Method for selective development of complex-structure deposits of solid minerals involves formation of mine working at excavation of mine rocks by tunneling machine by mixed bottomhole forming a cut and an additional exposed surface with a cutting actuator, and subsequent destruction of the face by an impact action actuator. Selective development of ore vein and mineralized enclosing rocks is carried out simultaneously, at that positioning of rotary frame on hinges relative to vertical axis is performed by means of hydraulic cylinder considering angle of incidence of ore vein. Cutting actuating element is installed in the front part of heading machine. Grooved mass of ore vein loosened with cutting actuator is poured into accumulator, and rock mass of mineralized enclosing rocks, pierced by actuating element of impact action, is poured into container.

EFFECT: technical result consists in improvement of productivity and process efficiency by increasing functionality, reliability and providing selectivity of extraction of thin ore veins, reduced impoverishment, reduction of environmental load on environment in area of mining operations.
