Traditionally, mines and quarries have lacked a practical method of describing blast results. Adjectives such as good, fair, or poor do little to define performance, and sieving and/or counting particles was too costly and time consuming to be considered a viable alternative. Recent advances in imaging technology along with ongoing research and development by Franklin Geotechnical Ltd., ETI Explosives, INCO and the University of Waterloo have created a digital analysis system that generates a fragmentation size distribution curve from muckpile images. These images are acquired on a videotape or still photo format and can be automatically processed by grabbing the image, scaling it and defining the block edges through a series of routines to quantify blast fragmentation. This technique is ideal for evaluating oversize reduction programs, pattern optimization efforts, prevention of overblasting and fines generation or just benchmarking. This paper will describe the WIPFRAG System and illustrate by means of actual case studies, the usefulness of this tool.
