SELF-PROPELLED MOUNT FOR COVER OF BLAST PLACE Russian patent published in 2001 - IPC

FIELD: mining art, in particular, blast breaking of rocks and blasting operations in strained conditions. SUBSTANCE: the self-propelled mount comprises a vehicle in the form of a carriage with a supporting platform accommodating a dust collector and an adsorber, vertical frame with enclosing components for closing the grate ports in the form of flexible reservoirs filled with loose material, coupled to the supporting platform through a counter-recoil mechanism for its motion and inclination relative to the supporting platform, and a sectional horizontal frame, suspended by ropes from the beam of the supporting platform, with flexible reservoirs with liquid and pneumatic pockets having relief valves for release of liquid under pressure to a sealed reservoir installed on the horizontal frame above the flexible reservoirs. The novelty in the mount is the suspension of the flexible reservoirs with liquid in the grate ports by chain nets, and fixing in the ports of the vertical frame of massive hollow rods with initiating devices passing into the hole charges. EFFECT: enhanced reliability and level of environment protection in blasting operations. 3 dwg
