Cast Blasting critical parameters are: 1) powder factor (this in turn depends on the burden, spacing and hole diameter),
2) drill hole angle, 3) stemming height and material, and 4) initiation mode. To fine tune parameters for optimal Cast
Blasting results, the authors performed further trials by using a computer simulation program (DNA-Blast). This is a
very interesting approach in terms of cost and delay. The combination of parameters used in simulation is given in the
following table:
