ABSTRACT
With the rapid advance of image processing technology, systems which generate fragmentation indices relating to images of blast muckpiles have drawn a great deal of interest. Optical systems are well suited to measuring cross-sectional areas of larger fragments where the perspective and optical quality of image is good. However, output purporting to represent mass should be viewed with caution, and the higher the percentage of fines, the less useful optical systems are likely to be. Misunderstanding the limitations of such systems will sometimes lead to entirely wrong evaluations being obtained.
