DYNOCONSULT AND DYNOMINER™ PROVIDE
UNDERGROUND SOLUTION

PROJECT SUMMARY
WITH DYNOCONSULT’S KNOWLEDGE AND
THE DYNOMINER LOADING SYSTEM, THIS
UNDERGROUND MINES EXPECTATIONS WERE
MORE THAN MET
A desire to reduce operating costs by converting from
packaged to bulk explosives had this underground
limestone operator running trials using different explosive
companies. The mine operator also wanted to decrease
the time required to load the heading rounds in order to
improve the efficiency of the blast crews thus improving
production through an increased number of rounds
blasted per day.

CASE STUDY

The TITAN® 1000 G gassed emulsion was introduced to
speed the loading of wet holes, and quarry personnel were
trained to operate the DynoMiner underground loading
system. By using compressed air instead of hydraulic
pressure, the DynoMiner underground loading system
was able to operate using existing mine air systems, which
greatly simplified the drilling and loading procedures.
Since the entire DynoMiner unit and components are self-
contained, quarry personnel found their movement in the
mine to be both safe and efficient.

By using TITAN gassed emulsion the density of the loaded
product was able to be adjusted from 0.80g/cc to 1.20 g/
cc, providing added flexibility for this mine operator. As a
gassed emulsion product, the TITAN emulsion is classified
as an oxidizer until it is sensitized in the hole, providing the
 The combination of DynConsult’s knowledge and the
ultimate safe product for underground applications.
 DynoMiner offered significant improvements to this
 hardrock mine operator, resulting in reduce costs and
 improved productivity.
 VALUE ADDED
FASTER LOADING WITH DYNOMINER AND
INCREASED ADVANCE WITH TITAN GASSED
EMULSION EQUALS A WIN FOR THIS MINE
The trial outcome was that this mine operator chose the
DynoMiner as the bulk delivery system for their operation.

The customer affirmed that the DynoMiner system was
much easier to use and maintain than the competitor’s
system. With the use of the DynoMiner, there is the
potential for an explosives savings cost of 30% for this
mine.

When compared to their previously-used packaged
explosives, the DynoMiner allowed the blasters to
reduce by 50% the time required to load the wet holes
of the pattern. The face advance of the blasts monitored
increased by 10% without any change in the perimeter
limits of the heading.

Furthermore the DynoMiner offered an easier method
of loading than stick powder, since no lifting of heavy
boxes was required. The preparatory work required at the
beginning of the shift was reduced since bulk materials
are quicker and easier to handle.
