BUNTON-FREE REINFORCEMENT FOR VERTICAL SHAFT Russian patent published in 2004 - IPC

FIELD: mining industry, in particular, shaft reinforcement constructions.

SUBSTANCE: bunton-free reinforcement for vertical shaft has conductors arranged in the vicinity of vertical faces of lifting containers between side and front walls, at an angle to longitudinal axis of lifting container, and anchor cantilevers fixed in shaft timbering. Supporting construction is mounted thereon for moving along anchor cantilever rods to be adjusted in radial direction. Conductor is attached to supporting construction so that its position relative to anchor cantilever may be adjusted in three mutually perpendicular planes. Reinforcement of such construction may be used in vertical shafts of coal mines and in underground constructions of miscellaneous purposes.

EFFECT: reduced usage of metal in construction, decreased labor intensity in mounting works, and reduced air-flow resistance to ventilation flow.
