Abstract

This paper describes a practical technique to estimate the size distribution of large volumes of rock fragments, including blasted benches, waste dumps and heap leach sites. Images are obtained from a site using a standard video camera and downloaded onto the computer. Image processing algorithms are used to delineate the individual rock fragments in the images, followed by the calculation of the area and shape of each fragment. Statistical calculations are then performed to estimate the complete size distribution of the fragments. The accuracy of the technique has been assessed with a number of field validation studies. -Author
