3-D numerical modelling of radial-axial rock splitting

Radial–axial rock splitters are potential primary mechanical excavating tools for underground hard rock mines. In an effort to further guide the development of a working prototype, a series of laboratory, field, and numerical experiments were conducted. The results of a three-dimensional finite element analysis of a radial-axial splitter used to break intact granite blocks are presented. Numerical results are in good agreement with the physical modelling and field studies, thus validating the numerical formulation implemented. © Rapid Science Ltd. 1998
