Abstract
Distribution Analysis of Rock Fragments Size Based on the Digital Image Processing and the Kuz-Ram Model Cas of Jebel Medjounes Quarry
Highlights
Fragmentation is one of the most important concepts of explosives engineering
The results of fragmentation such as the rate of oversize fragments were studied using two different methods, the analytical method through the Kuz-Ram model and the numerical method through digital images in an image analysis system called Split Desktop® software. from the results found we note that the value of the oversize of the fragments found by the digital image processing is 11.21%, lower than that found by Kuz-Ram (31.95%), which implies that the numerical analysis of the images gives us a better results compared to the Kuz-Ram model, because it is based on the treatment of all the parts of the pile with the different granulometric classes of the rocks
Drilling and blasting are the most basis method of rock breaking used in mining operations and civil engineering in Algeria for the purposes such as: breaking of rock for mining; blasting for road construction; digging foundation in hard rocks
Summary
Fragmentation is one of the most important concepts of explosives engineering. Drilling and blasting are the most basis method of rock breaking used in mining operations and civil engineering in Algeria for the purposes such as: breaking of rock for mining; blasting for road construction; digging foundation in hard rocks. The blasting work in Algeria, especially blasting in mining engineering, blasting engineers usually deal with the blasting works which quarry out in benches. Blasting is the first step of the size reduction in mining and it is followed by crushing and grinding unit operations. The efficiency of these unit operations is directly related to the size distribution of muckpile. Reliable evaluation of fragmentation is a critical mining problem
