MIXED LIQUID EXPLOSIVE SUBSTANCE Russian patent published in 2018 - IPC C06B47/00 

FIELD: blasting operations.

SUBSTANCE: invention relates to the mixed liquid explosives of the simplest composition, manufactured at blasting sites and intended for use in the mining industry, as well as to the said liquid explosives preparation kit. Liquid explosive contains concentrated nitric acid as an oxidizing agent and one or more aliphatic or cyclic sulfones of general formula R-SO₂-R', as a reducing agent, where R and R' are independently alkyl with from 3 to 12 carbon atoms or R and R' are a divalent aliphatic unsubstituted or substituted radical with from 4 to 5 carbon atoms, together with SO₂ forming a cycle. Oxidizing agent to the reducing agent weight ratio is in the range of 50–200 % of the value corresponding to the zero oxygen balance.

EFFECT: invention allows to improve the industrial explosives energy and detonation properties, and also to increase their safety and reduce the impact on the environment due to their operational and technological characteristics.
