A large crusher is planned for the future, and this is expected to reduce boulder blockage. The primary quarry blasts are well designed and utilize closely controlled drilling and loading procedures. Blasting Mats. Blasting mats are devices for containing flyrock from a blast by catching the flyrock before it has a chance to escape.
Increasingly it has been realized that an efficient drilling and blasting program can impact positively throughout the mining operation from loading to maintenance, hauling to crushing, ground support to scaling and grade control to recovery. We will also test the concepts and increasing challenges of blasting in the vicinity of local communities.
