Energycondensed and granulated system Ukrainit-ANFO for trotil’s replacement in rock breaking PP267

Purpose and areas of usage
Energy - condensed granular system Ukrainet - ANFO is intended to replace TNT in the destruction of rocks in underground conditions. The system is characterized by a minimal amount of harmful explosive products, which is extremely important for mines with complicated ventilation

Main characteristics of development
Ukraine - ANFO has the appearance of gray granular gray to brown color and is characterized by high explosive performance: the critical diameter of open charge is 40 - 45 mm; heat of explosion - 3760 - 3820 kJ / kg; the speed of detonation in a steel shell - 3. 2 - 3. 8 km / s; at an explosive gas volume of 980 - 990L / kg, the amount of harmful gases in the explosion (in terms of conditional CO) is 27 - 38l / kg; the transition from deflagration to detonation in a closed volume is excluded; bulk density 750 - 950 kg / m3 at a temperature of 20 ± 10 °С; Fracture sensitivity on a Kop - K - 44 - III, ≥702 MPa

Main advantages of development
Developed technologies for modification of agrarian granulated ammonium nitrate provide a product with a uniform impregnation of granules without leakage and migration of the fuel phase for a long time (more than 3 months). As a fuel component used non - toxic products of vegetable fat processing, which do not smell oil products, the product does not contain TNT, aluminum, diesel fuel and mineral oils

Market demand
Ukraine - ANFO can successfully be used in underground mines for pneumatic charging of dry hollows and wells to replace the regular trotyl explosives, which allows to significantly reduce the use of hazardous in handling and toxic trotyl

The state of development
The technology of obtaining Ukrainit - ANFO is realized in the conditions of industrial production in accordance with the TU of Ukraine.
