The effects of poor blasting in open pit mining operations cannot be overemphasized. Not only does blasting induce vibrations, but the rock behind the slope face can also be fragmented and loosened as a result [12]. Also, the conventional method of blasting rocks is often accompanied by fly rocks, ground vibration, generation of
