Prediction of Rock Fragmentation in Open Pit Mines

In this paper, fragmentation of the rock after blasting is estimated analytically by the use of neural network method. The results obtained here, are compared with those predicted by Kuz-Ram and image analysis methods. All these have then been tested using real data gathered from Gol Gohar iron ore mine of Iran. It is shown that neural network

Investigation of the blast fragmentation using the mean

The fragmentation index is defined as: F I = X B x 50 where FI is the Fragmentation index, X B is average in situ block size, and x 50 is mean fragment size of muckpile resulting from blasting. The use of the fragmentation index as a tool to evaluate blasting efficiency was first introduced by Aler and coworkers [9], [10], [11].

equipment and drilling equipment, fragmentation tolerance, and production demands, will also influence the choice of explosives. Although a significant recurrent expense, the cost of explosives is usually only a small percentage of the total costs encountered in breaking, moving, and processing rock and ore. The small difference in the cost of a
