Reducing piles through better blasting
Blasting has four objectives: to loosen in-situ rock from a quarry face, reduce block size for processing by crushers, to excavate and load the blast pile and to leave a stable face afterwards. Efficient blasting also reduces fines and oversize and the fragmentation of the blast pile is designed to match the loading equipment and crushers.
