Main objectives of rock blasting are to fragment the strata for achieving required yield with desirable fragmentation and minimum side effects. Though the side effects like ground vibrations, noise, fly rock, etc. cannot be avoided completely, these can be minimized by selecting suitable explosives, initiating devices and using proper blast design in given geo-mining conditions. Higher intensity of unwanted results indicates improper utilization of explosive energy in the fragmenting process, as the total amount of energy released by unit quantity of explosive is constant.
