This simulator depends on equations which are based on the fundamental laws of Physics, of Chemistry, and of Rock Mechanics.  It simulates the contour of the shock wave stress created in the rock mass;  for a given bench blast procedure, the contour of your choice of shock wave stress level T is simulated, and displayed graphically inside the bench.  With the choice T=To, the dynamic resistance of the given rock, it is possible to predict blocks in the collar zone, toe, possible back-break, etc.  This, together with other parameters explained below, helps to predict the proper burden, collar length, subgrade drilling, the choice of explosive types and their distribution, as well as to evaluate the quality of a final wall. With the choice of other values of T, it is possible to improve the fragmentation in a given zone of the bench.
