Purpose of the development: Transfer of the Ukrainian mining industry to the use of advanced technologies for obtaining and applying highly effective waterproof explosives.

Recommended application field: Iron ore mining and processing plants, mining enterprises.

Technical characteristic: Physicochemical and explosive characteristics of EVB. Indicator name - Norm. Appearance at a temperature of 20 ° C to 70 ° C. Flowing homogenous gasified mass from yellow to brown. Density at temperature (40 ± 10) ° С after 1:00 after sampling, kg / m3 - 1100-1410. Relative density at temperature (40 ± 10) ° С after gas generation for a time not more than 1: 00,%, not more than - 94. Completeness of detonation of a charge in a paper or plastic shell with a diameter of 100 mm from a detonator-mark of the T-400G or TG-500 brand is FULL. Heat of explosion Qwib, kJ / kg - 2940-2960. Detonation velocity, m / s: - in the steel sheath - 5200-5300; - in the paper shell - 4800-5000. Sensitivity to shock after gas generation according to GOST 4545-88:    - the lower limit on the device No. 3, mm, more - 500;    - frequency of explosions (at Р = 10 kg, Н = 250 mm) on the device № 3,% - 0. Sensitivity to friction after gas generation:    - lower limit, MPa (kgf / cm2) - 668 (6810);    - frequency of explosions at a compression pressure of 668 MPa,% - 0. Water resistance (on contact with water 24 h) g / cm2, not more than - 0,02.

Advantages over analogues: Highly effective waterproof explosive substances in terms of capacity, safety, ecological purity and economic efficiency significantly exceed the existing domestic and the best world analogs.

The development stage readiness: Ready for application

Description of the development:
()
The transition of mining enterprises to the use of emulsion explosives provides: - elimination of the need for storage in warehouses and operations for their transportation to places of use; - independence from the import of raw materials for the manufacture of explosives; - increased safety of blasting due to low sensitivity of emulsion explosives to mechanical effects; - elimination of groundwater contamination in the presence of emulsion in the well; - a significant improvement in the state of the environment.
