A Novel Concept for a Rock Breaking Machine. II

the rock could be extracted satisfactorily, and in geometries of low confinement, this could be accomplished with high efficiency. In concrete-breaking, no problems were encountered in breaking the concrete itself but, if present in a three-dimensional array, the reinforcing bars could cause trouble. Tests with the largest machine confirmed its
