COMBUSTIBLE REAGENT OF GAS GENERATOR FOR DRILLING AND BLASTING OPERATIONS Russian patent published in 2003 - IPC

FIELD: mining jobs, applicable for instance in breakage of outside stones and boulders, structures from brick, concrete, cutting of dimension stones and stone blocks, tunneling, in mineral mining and mining of useful minerals and precious and semiprecious stones. SUBSTANCE: combustible reagent of gas generator is made in form of device with through channels oriented along its axis. Channel wall thickness is characterized by relation ship according to which, this value is selected as quotient of division of product of experimental coefficient by bulk density for loose material and true density for liquid of used oxidizer, by product of combustible reagent material density, by stoichiometric oxidizer to combustible member weight ratio, and area of channel cross-section equals product of experimental coefficient by squared channel wall thickness. EFFECT: reduced labor input in manufacture of combustible reagent and labor input as a whole. 10 cl, 7 dwg
