Blast vibration has long been associated with quarries but separating fact from fiction has often been a problem Blasting is necessary to break rock from the ground prior to it being taken for processing The shock waves generated not only direct much more energy into breaking up the stone effectively and less into sound and air Larger quarries may blast once a day and smaller quarries may blast once or twice a week Blasting is monitored with a special machine to record sound and vibrations so that the community around our quarry remains protected and safe The blasts that occur when the explosives are set off free the stone from the quarry wall
