Water-containing explosive substances

WATER-CONTAINING EXPLOSIVE SUBSTANCES (EN: explosive slurry; DE: wasserhaltige Sprengstoffe; FR: explosifs aqueux; ES: explosivos acueos; RU: водосодержащие взрывчатые вещества) are the explosive substances, which are based on the ammonium nitrate, and are plasticized using the aqueous gelatin. These substances have been proposed for the first time by the American scientist Melvin A. Cook during the 50-ies of the 20th century. Within the USSR, there are categorized as the water-containing explosive substances the aquatols, aquanites, aquanals, ifzanites, carbotols, and within the USA and Canada, the Powerex, Towex, Hydromex, DVA, airymight, airygel, and so on.

They use the water-containing explosive substances for the opencast and underground works within the dry and water-flooded strong rocks, where is necessary the high concentration of the energy of the explosion. Depending on the content and viscosity of the gelatin, they distinguish the viscously flowing, jelly-like, and highly viscous plastic water-containing explosive substances.

They produce the viscously flowing water-containing explosive substances at the place of the usage, and they produce the plastic and jelly-like water-containing explosive substances (aquanites, aquanals) under the industrial plant conditions; they issue these substances within the polyethylene packaging in the form of the cartridges with various diameters (mostly 160-200 millimetres). The water-containing explosive substances ensure the high density of the charging into the blastholes and boreholes, which is near to their own density, and these substances ensure the high voluminous concentration of the energy within the charging chamber. The usage of the water-containing explosive substances at the individual mining enterprises reaches 20% of the total quantity of the explosive substances, which are used.
