METHOD FOR PRODUCTION OF WATER-CONTAINING EXPLOSIVES Russian patent published in 2003 - IPC

FIELD: explosives. SUBSTANCE: invention relates to industrial explosives and can, in particular, find use under mining conditions when blasting operations are involved. Explosives are prepared by a method comprising: dissolving oxidant or part thereof in water, densifying oxidant solution with polyacrylamide, mixing dense solution with combustible and undissolved part of oxidant, structuring mixture with chromic salt, and transferring it into hole. According to invention, densified oxidant solution containing 0.8-1.5% polyacrylamide at temperature superior to its saturation temperature is supplemented by alkali in amount 0.01 to 0.15% and above-indicated mixing is performed simultaneously with transferring explosive into hole. EFFECT: enabled preparation of explosive with good flowability capable of being pumped, physically stable and water- resistant. 8 cl, 1 tbl, 3 ex
