Pumped "SLURRY" explosives
Pumped "SLURRY" explosives type "oil in water".
- MAJDANIT 10
- MAJDANIT 20
MAJDANITS are produced on the SLURRY pump-truck, acting like a small mobile factory for explosives.
The filling of SLURRY pump-truck is connected to its base-SLURRY station, ware all he components are prepared.
None of the starting components is explosive
Thees explosives are waterproof and they get their functions only after being pumped into a mine hole in which they reach the diameter of the hole (larger than critical) and density that allows stable detonation.
Their power can be moderated according to demands of rock mass. They are used for mass blasting on open pits with diameters bigger than 100mm.
They are not sensitives to blasting cap N° 8 and to detonating cord.
Initiation is done with pentolite boosters (PP-360 and PPN-500).
Long keeping in boreholes is not recommended, but mining as soon as the proper conditions are obtained.
