Abstract
In this paper the procedure for the determination of drilling and blasting patterns in general and that for Meiduk copper mine in particular, has first been described. Geological and the geotechnical data for the mine, together with all other relevant information such as working conditions in the region, particulars of the available equipment and characteristics of permitted explosives have all been discussed. Using the available data and the results of experiments carried out on site, an optimized pattern has been found with the help of conventional hand methods. A computer program is then introduced that also uses additional parameters such as particle size distributions after blasting. This program has also produced an optimized pattern. The two patterns have been applied to Meiduk copper mine and their results have been compared. The procedure can be applied in all similar mining situations where drilling and blasting constitutes an important element in the total mining costs.
