Mining methods – Recovering the minerals from the ground
Drilling & Blasting - Overview
Minerals occur in the ground, most often in rock. To extract them it is necessary to use explosives of all kinds to blast the rock so that it can be handled by large mining equipment. Before blasting can take place holes must be drilled in the rock for the explosives to be placed. And all this must be done in a safe and scientific manner. This lecture describes the “In’s and Out’s” of drilling and blasting.
