DigiShot Plus Case Studies
Largest DigiShot Plus Electronic Blast at Optimum Colliery
APPLICATION: Coal mine
LOCATION: Mpumalanga, South Africa
PRODUCT: DigiShot Plus
SOLUTION: A successful trial blast was done by AEL Mining Services using the DigiShot Plus electronic initiating system at Optimum Colliery, situated ± 40km East of Middelburg in the Mpumalanga Province during 2010.
With the DigiShot Plus electronic initiating system, logging of the holes can start while the MMU's are still busy charging resulting in less downtime for the earth moving equipment such as loaders and draglines. The mine was impressed with the new electronic system and realise the benefits in terms of risk and connecting time reduction. By setting off the blasts remotely, they have a much clearer view of the area being blasted, thus an additional safety measure. The mine is also able to clear the area without the risk of damaging any connecting wires from the bench box to the blasting area which in turn also provides cost saving opportunities to the customer. From a post blast analysis done, a significant improvement in fragmentation uniformity and size distribution was noted. Contributing factors to the improved results was the combination of the AEL SD135E bulk formulation and the DigiShot Plus electronic detonator system. This was the largest blast ever done with the DigiShot Plus system to date.
