· The depth of the crushing pit will decrease with the growth of the impact angle. The reason is that the vertical energy of the ASJ becomes smaller at the large impact angle. The depth of the crushing pit will increase with the growth of the impact time and the jet pressure, because both of them can improve energy of the ASJ to impact the rock.
