Description

The DynoTracker is a device that attaches to the end of a standard charging hose
used for loading ANFO. This device allows the use of ANFO instead of expensive 12

 Tube Explosives
cartridge explosives as perimeter charges in tunnelling applications.

technique. It loads a partially loaded (decoupled) charge of ANFO into "low
inclination" drillholes such as those employed in jumbo development mining. The 6
decoupled charge produces a low order explosion when the primer detonates.
This is ideal for the control of perimeter blasting, resulting in smoother tunnel 4

Features and Benefits Recommendations (cont’d)
 The use of DynoTracker allows a low cost alternative to conventional tunnel Water - Ensure there is no water in perimeter holes, as water will quickly dissolve
 perimeter charges in dry ground. the decoupled charge of ANFO.  Inventory can be rationalised as the need for tube type charge is eliminated. Loading - Reduce the air pressure on the ANFO loader to ~30psi, depending on
 the hose length. Insert the DynoTracker into the hole, keeping it pressed against
 Reduced hanging material remains on the perimeter after blasting,
 the toe charge. Load through the DynoTracker while retracting the loading hose
 reducing overbreak, scaling time and support requirements. as per normal blow loading practice. This results in a decoupled “string” of ANFO
 Inventory is reduced in the magazine and time is saved in loading explosives in the hole. onto the charge up vehicle.  No additional equipment is required on the charge up vehicle, e.g. extra Safe handling, transportation and storage

reduce any butts. Transportation and Storage – There are no specific storage requirements or
 constraints other than those associated with any electronic device. Attachment - Ensure the end of the loading hose is cut square before screwing
on the DynoTracker. The device is easily attached to/detached from a standard
26mm OD semi conductive charging hose. Test the connection before loading.
