BLASTCAD - NORANDA 3-DIMENSIONAL COMPUTER-AIDED UNDERGROUND BLAST DESIGN SYSTEM

This paper describes the progress accomplished at the Noranda Technolo gy Centre in the field of three-dimensional computer-aided underground blast design. Traditional methods of laying out underground blasts ar e reviewed, and the new computer-aided approach is described. Time sav ings achieved through the use of BLASTCAD can be advantageously used t o better engineer blasts, using models and blast vibration analysis. F uture work involving the attachment of blast models directly to the sy stem is also addressed.
