In previous papers I described that the radial compressive stress
rr produced in rock by the explosion is proportional to
r-
1.3, where
r is the distance from the point in quesion to the center of the bore hole, by experimental studies performed at a limestone quarry.
This paper discusses the relation between the stress
rr and the distance
r from a theoretical point of view. This relation varies not only with the distance
r, but also with the shape of bore holes in which explosives are charged.
