The hazards of surface blasting are primarily due to lack of blast area security, flyrock, premature blast, and misfire. Blasting generally entails two purposes: rock fragmentation and displacement of the broken rock. The displacement of the broken rock depends on the shot-design parameters, geological conditions, and mining constraints.
