METHODFOR VENTILATION OF DEEP QUARRIES Russian patent published in 2023 - IPC E21F1/00 

FIELD: mining.

SUBSTANCE: used for ventilation of deep quarries. The method includes the organization of air exchange between the quarry atmosphere and the environment by forcing air through underground mine workings by the operation of fan units. In the tunnel, a system for fixing the rollers is installed, which consists of axles with rollers and guides, which are made in the form of grooves placed in trenches, which are made equal to the width of the axis and directed along the tunnel. A fan with an insulating element is installed at the junction of the inclined working and the tunnel. The pipeline is pulled out of the tunnel along the rollers, fixed at the mouth of the tunnel with an insulating element. The end of the pipe is attached with a support rope to the surface of the quarry wall, air is supplied until the concentration of pollutants in the pollution zone decreases, after which the air supply is stopped, and the pipeline is pushed into the tunnel.

EFFECT: increasing the efficiency of ventilation of the quarry space.
