Abstract

This investigation proposes modifications to improve the perforation and blasting works being carried out in the Pilon quarry in order to decrease the number of oversized rocks during the fragmentation of the rocky massif for further grinding and classification. The values established in the Manual for Blasting and Perforation of Rocks were proposed to be modified, which is consistent with the characteristics of the quarry under investigation. This resulted in a reduction of oversized rocks by up to 5%. This accounts for savings of 2,02 $/m3.
