in this research, first of all, the existing problems in fragmentation measurement are reviewed for the sake of its fast and reliable evaluation. then, the available methods used for evaluation of blast results are mentioned. the produced errors especially in recognizing the rock fragments in computer-aided methods, and also, the importance of determination of their sizes in the image analysis ...

The purpose of this study is to measure the size distribution of blasted rock using the digital image processing software “SplitDesktop system” in order to evaluate the efficiency of blasting operation. Site of study is a limestone quarry producing limestone for cement manufacturing. Fragmentation is the ultimate measure of efficiency of any production blasting operations. The degree of fragmen...
