THE INDUSTRY’S MOST POPULAR HIGH SPEED CAMERA!
Blasts and their effects occur too quickly to be captured with standard speed video cameras. To see what you’ve been missing – you must record your blasts with high speed video.
If you want to determine the effects of blasts on structures or vehicles or determine the actual firing times of your blastholes and the nature of the rock movement, the digital video camera with the speed and resolution to accurately capture these events is the Blaster’s Ranger 3™ High Speed Camera. It is a complete high speed video recording system with an easy-to-use operator interface.
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.

The camera is designed to capture high speed digital video, enabling detailed analysis of blasting events such as detonation timing, top rock movement, displacement of blasted rock mass, stemming effectiveness and flyrock trajectory. It provides sub-millisecond precision and playback at reduced speeds for thorough study.
Camera will automatically power on when power is attached with sufficient power.
