    Rock hammering is slow, inefficient, costly, and has the same inherent properties of blasting on a smaller scale. Blasting can actually be quieter than rock hammering, and takes much less time. A typical blast duration is usually 1 to 3 seconds, while rock hammering can take over two weeks to displace the same amount of volume incurred by a single blast.
