The DynoTrackeris a device that attaches to the end of a standard charging hose used for loading ANFO.
This device allows the use of ANFO as a perimeter charge in tunnelling applications. Hereby eliminating more expensive cartridgedexplosives.
ANFO is blow-loaded through the DynoTrackersimilar to the normal blow-loading technique.
It loads a partially loaded (decoupled) charge of ANFO into "low inclination" drillholessuch as those employed in jumbo development mining.
The decoupled charge produces a low order explosion when the primer detonates. This is ideal for the control of perimeter blasting,resulting in smoother tunnel walls with less overbreak.
- Construction Aluminium
- Length (mm) 375
- Diameter (max) (mm) 30
- Weight (g) 370
The use of DynoTrackerallows a low cost alternative to conventional tunnel perimeter charges in dry ground.
- Inventory can be rationalised as the need for tube type chargeis eliminated.
- Reduced hanging material remains on the perimeter after blasting, reducing overbreak, scaling time and support requirements.
- Inventory is reduced in the magazine and time is saved in loading explosives onto the charge up vehicle.
- No additional equipment is required on the charge up vehicle, e.g. extra pneumatic loader for PS products.
