Appropriate choice of an explosive is critical in blasting to come out with stable excavations at the same time meeting production requirements Since inception the studied mine has been using ANFO as the main blasting agent in primary blasting As mining progresses there is a general
retention of the bubble energy will result in more work done to the rock mass and will reduce the velocity and range of flyrock The overall goals of the blasting program are The overall goals of the blasting program are
