In the 1960s, there was a large push to determine different sonic velocities of rock in order to match the velocity of the rock to the velocity of the explosive. In addition to this, some authors went on to develop equations and models to predict minimum and maximum bench heights based on the explosive velocity, rock velocity and primer location.
