Title

Investigation into the Effect of Varying Joint Aperture and Nature of Surface on Pre-Splitting

Abstract

The Rock Mechanics and Explosives Research Center of the University of Missouri-Rolla conducted further research into the mechanism of presplit blasting. The research comprised of modeling both closed and open joints between 3/8 inch blastholes loaded with 15-grain per foot PETN detonating cord. The precision ground joints were modeled thus simulating tight fractures as found in real rock mass. Precision ground joints of varying thicknesses enabled to create opening between the joint surfaces.
