Ground motion data from single, cylindrical explosions with the same source configuration as the individual explosions that make up a production mining blast array are analyzed. Strong shear motion is observed which can not be accounted for by the simple explosion source. Spall (the detachment and slap-down of the near surface strata and the separation of the burden and overburden from the continuum) accompanying the explosion seems to play an important role in shear wave energy generation. These shear energy may be the most damaging to the structures near the production site.
