Abstract

A wave superposition code was developed to calculate stresses explosivley induced by long, multiple blast holes within a three dimensional rock mass. Computed stresses were found to correlate with measured fragmentation from fourteen cases in coal cyclotherm geology when actual, rather than planned, initiation times were modelled.
