SOME APPLICATIONS OF HIGH-SPEED VIDEO FOR THE
OPTIMIZATION OF BLAST RESULTS BLAST
FRAGMENTATION High-speed video assists the
blaster in isolating the origin of oversize
boulders as well as potential muckpile toe
problems that can be produced by excessive front
row toe burdens. Geological effects can commonly
be evaluated, for example, by relating face
venting to rock structure and inherent planes of
weakness. The onset and velocity of blasthole
stemming ejection can normally be easily measured
providing a comparative estimate of energy loss
at the top of the blasthole. At the same time,
cratering and doming at the blasthole collar can
be evaluated allowing a visual check on collar
designs. Accordingly all of the major blast
design parameters can be assessed. Cast blasts
can be enhanced with respect to throw, range, and
direction with appropriately placed cameras. Coal
rib damage and coal loss can also be evaluated in
cast shots.

BLAST PROFILE Overall blast profile design can
be enhanced using high-speed videos concentrating
on material trajectory and velocity versus front
row burdens and timing analysis. BLAST
TIMING High-speed video may be used to assist in
determining the optimum blast delay time and
detonating sequence. Appropriate camera locations
can allow determination of the onset and velocity
of movement of both the blast surface and blast
face. Cast blast results can readily be enhanced,
blast choking can be mitigated and blast
backbreak reduced, which will be found
of particular importance when producing final pit
walls.

EXPLOSIVES AND ACCESSORIES PERFORMANCE High-speed
video may be used to determine delay firing
times and delay scatter as well as to confirm if
the units are firing within manufacturers
tolerances. In conjunction with in-hole velocity
of detonation measurements, high-speed video can
be employed to help evaluate explosives
performance. Detonating cord can be tested for
detonation by checking poor knotting practices
and reverse angles or kinks. Forces involved when
poorly tied knots become undone during detonation
can be observed. BLAST ENVIRONMENTAL
FACTORS Evaluation of a number of environmental
factors can be assisted by using high-speed video
including the source of flyrock and dust
generation the source of backbreak and gas
damage detrimentally affecting pit wall
production noise and air blast produced from
surface or face bursting and identification of
the source of noxious fumes generation.

SPEED and RESOLUTION for BLASTING Colour and
monochrome models are available with recording
speeds of up to 1000 fps at a full resolution of
640 x 480 pixels at all speeds. For a higher
resolution Blasters Ranger-HR with 1280 x 1024
is available. PORTABILITY for BLASTING The
Blaster's Ranger fits in one hand and has a
fully integrated 127 mm (5 in.) LCD colour
screen. Four 4 internal D-cell batteries will
provide power for 90 minutes with longer
operational times available using external 6 VDC
battery or AC power. EASY-TO-USE for
BLASTING The on-screen menu and camera buttons
provide complete camera control and make
capturing the blast in slow motion detail a very
simple procedure. After the blast the video can
be played back in slow motion detail on the
screen and can be saved digitally to a removable
CompactFlash card and/or downloaded to a computer
using USB-2 for subsequent storage, play-back and
motion analysis.

INDEPENDENT BOTTOM AND SIDE VIEWS Rugged,
waterproof Probe contains both side and bottom
colour cameras and independent LED illumination
providing ample light for recording
high-resolution digital video of deep cavities
and cracks in the bottom and sidewalls. PORTABILI
TY Installs at the borehole in less than 3
minutes. Control Unit contains fully integrated
digital video recorder, LED lighting controls
including dimmer, camera controls and
rechargeable batteries. 100 DIGITAL RECORDING
In the comfort of your office, download digital
video from the integrated digital video recorder
via Firewire to your PC for subsequent storage,
play-back, presentation and analysis. EASY-TO-USE
The simple on-screen menu and Control Unit
switches and buttons provide complete camera
control and make recording the borehole video to
digital video tape a very simple procedure. If
you can operate a VCR or camcorder, you can
operate the ExplorerTM. BLASTERS NOW YOU KNOW
Instant detection of cracks, cavities and
irregularities. Locate ore/waste boundaries.
Locate coal seams and top of coal. Locate weak
and strong geological structures. Answer these
questions is it a wet hole or dry hole? and
are we out of the water yet? and why isnt my
explosives column rising?.

• The Explorer is an optical scanning system
  specifically designed for inspection of both the
  bottom and sides of boreholes.
• The system is ideal for all applications that
  require a high-resolution colour image of the
  borehole and its sidewalls. The Explorer's unique

Wireless Trigger
Problem Many recording applications require the
instrumentation to begin recording upon receiving
a trigger command either from the operator or
from the event being recorded. It is often very
labor intensive and quite impractical to run one
or more trigger signal cables over long distances
and difficult terrain. Solution Portable
wireless transmitter and receivers that consist
of a transmitter located either near the event or
near the operator, that when triggered emits a
low power, wireless trigger signal which is
received by one or more receivers connected to
the standard trigger inputs of the
instrumentation.
17
Wireless Trigger
The Portable Wireless Trigger (PWT) is an
easy-to-use and convenient method for the
operator to trigger 1 to 4 remotely located high
speed cameras or other instruments. The PWT
consists of wireless Transmitter and Receiver(s)
that consist of a transmitter located either near
the event or near the operator, that when
triggered emits a low power, wireless trigger
signal which is received by one or more receivers
connected to the standard trigger inputs of the
instrumentation.

Wireless Trigger
Typical Useage Automated Triggering Typically
the Transmitter is located close to the event. A
short trigger line or a TTL signal line is
connected between the event and the Transmitter.
The Receiver(s) are located at a remote location
from the event near the instrument(s) and
connected to the external trigger inputs of the
instrument(s). When the trigger signal is
received at the Transmitter it sends a trigger
signal to the Receiver(s) that relay the trigger
signal to the instrument(s). Manual Triggering
Typically the Transmitter is located close to or
with the Operator. A push button trigger switch
is attached to the Transmitter. The Receiver(s)
are located at a remote location from the
Operator near the instrument(s) and connected to
the external trigger inputs of the instrument(s).
When the Operator pushes the push button trigger
switch the Transmitter sends a trigger signal to
the Receiver(s) that relay the trigger signal to
the instrument(s).
