Question Why is Blasting necessary? Answer When a blast is detonated some the explosive energy not utilized in breaking rock travels through the ground in all directions as wave motion similar to the ripple created in a pond when a stone hits the water This wave motion or ground vibration as it is commonly called travels mainly along
