CHARGING METHOD OF EMULSION EXPLOSIVE COMPOUNDS

摘要

FIELD: explosives. ^ SUBSTANCE: method provides for delivery of emulsion explosive by means of pump to charging hose and during transportation via the latter of components of emulsion explosive components the supply to annular gap between the hose wall and the flow of water composition with surface-active substance. Alkyl benzene sulphonate (NP-1 sulphanole) or alkyl sulphate of secondary alcohol (penta-surface active substances) in quantity of 0.05-0.1% is used as surface active substance. ^ EFFECT: introduction of surface active substances allows reducing inter-phase surface tension between emulsion explosives and wall of charging hose, which considerably reduces the pressure during the charging process and excludes the break of the charging hose. ^ 2 cl, 1 tbl
