Abstract

The paper represents a physical BLASTING model in laboratory scale along with a photographic approach to describe the distribution of blasted rock materials. For this purpose, based on we bull probability distribution function, eight samples each weighted 100 kg, were obtained. Four pictures from four different section of each sample were taken. Then, pictures were converted into graphic files with characterizing boundary of each piece of rocks in the samples. Error caused due to perspective were eliminated. Volume of each piece of the blasted rock materials and hence the required sieve size, each piece of rock to pass through, were calculated. Finally, original BLASTED ROCK SIZE DISTRIBUTION was compared with that obtained from the photographic method. The paper concludes with presenting an approach to convert the results of photographic technique into size distribution obtained by seive analysis with sufficient verification.
