Blast optimisation pays off for AfriSam’s Eikenhof Quarry
Due to the complex nature of its geology – characterised by extremely hard andersite rock containing joint planes which damage easily, creating voids on the back and side walls of each blast – AfriSam’s Eikonhof Quarry has traditionally struggled with both big boulders and limited fines in its blasts. In order to overcome the problems, the quarry has implemented a blast optimisation programme with great success. Munesu Shoko was recently on site and filed this report.
