can supply detonators containing an electronic delay. The use of these
detonators will allow the user to more accurately control the firing
time of individual explosive charges thus enabling the firing of very
sophisticated blast designs offering the user a much greater degree of
control over environmental disturbance and fragmentation.
Two different systems can be made available to users.
The Hotshot system is a fully auto-programmable system made by Detnet.
This system has been designed to allow the blast designer to fire all
types of surface mining or demolition blasts. Users familiar with
non-electric systems find conversion to this system very easy. Hotshot
has been made to replicate as far as possible the concepts behind those
non electric systems, it only has to work with delay intervals.
An additional feature of the Hotshot system is the high level of
security needed to fire the blast. Two security codes are needed to
fire any blast.
An alternative electronic detonator that can be supplied is the fully programmable Daveytronic
system made by DaveyBickford. This is a two wire
non polarised system.
These detonators are individually programmed by connecting each
detonator in turn to a programming unit. Once programmed the detonators
are clipped on to the firing line laid out along the rows. The
programming unit also operates as a testing unit. These detonators have
a maximum delay time of 14000ms and up to 1500 detonators can be fired
from one blasting machine. All functions of each detonator are tested
prior to firing.
