The simulator < Vibshock > depends on equations which are based on the fundamental laws of Physics, of Chemistry, and of Rock Mechanics.  It simulates the vibrations which propagate through the rock mass starting from the region of the blast hole, caused by the shock wave created by the action of the explosion; it calculates the particle velocity U of the rock at a given distance D from the blast hole, resulting from the passage of the shock wave.  This vibration is that which usually causes the major perturbation at short distance from the hole. 

The simulator < Vibshock > is not yet accessible on the web, but results of simulations with it can be supplied on demand.
