How To Break Rock Without Explosives
We can break rock with a sledgehammer, and a detonation pressure is our explosive hammer. As density increases, the “weight of the hammer” increases; as velocity increases, we “swing the hammer” faster and harder. We can move rock with a bulldozer, and gas pressure is our explosive dozer. As density increases, the dozer gets bigger; as velocity increases, the dozer runs faster
