Blasting Principles for open pit mining

By accurately determining the blasting zones, explosives, blasting accessories, blasthole drilling and shovel and truck operations can be optimized with a subsequent substantial cost savings. The benefit of better fragmentation to the truck-shovel operations are measured in increased productivity adn decreased maintenance costs. From the maintenance poit of view there is less shovel breakdown, less replacement of crowd transmissions, better dipper life and increased teeth and adopter life. The dumper benefit from less impact on the box during loading of smaller sized chunks and dumper operators appreciate the gentler loading resulting from the finer muck.
