The introduction of the
high accuracy detonator is reinforcing proper timing
as a fundamental element of efficient blast design.
The controlled sequence of hole-detonation is one of
the more critical parameters having a direct effect
on overall blast performance in many ways. The measure
of the potential effectiveness that the available explosives
energy has to both break and displace the rock mass
is directly proportional to the effective burden that
energy must overcome. Any variation in-hole detonation
timing will result in burden to energy relationships
that can have adverse impacts on the performance of
a blast. The results of these impacts have been witnessed
in the past as: poor rock fragmentation - high ground
and air vibration levels - fly-rock incidents - increased
need for secondary blasting and increased excavation
and crushing costs.
Research has shown that the standard pyrotechnic delay
elements that are currently being utilized throughout
the world do not provide the accuracy’s necessary
to consistently and measurably mitigate impacts.
Recent studies conducted using the Daveytronic®
programmable digital detonator have concluded that accurate
hole detonation would provide the explosives using industry
with the potential to effectively minimize these adverse
timing related impacts.
