MOBILE INSTALLATION FOR LOCALIZATION OF EXPLOSION Russian patent published in 2004 - IPC

FIELD: drilling and blasting operations in hard rocks, applicable in various branches using blasting operations in rock masses, in restricted conditions inclusive. SUBSTANCE: the mobile installation for localization of explosion has a vehicle in the form of a massive carriage with a supporting platform that carries a vortex dust collector and an adsorber, vertical lattice frame, whose lattice windows are covered by flexible reservoirs with loose material, linked with the supporting platform by hydraulic cylinders, counterrecoil mechanism and a supporting member with rollers for movement and inclination, horizontal lattice frame made of sections, with gas-permeable chain mats freely suspended from the lattice windows, linked with the beam of the supporting platform by wire ropes, provided with an apron and elastic housing forming a closed space above it. The novelty is in placement of hollow soft reservoirs with holes located one above another and successively interconnect to one another and to the chain mats. EFFECT: enhanced durability and reliability of device operation. 4 dwg
