The project will connect the Measured While Drilling data gathered during conventional tunnel drilling, Drill and Blast, with the blasting damage of the contour and floor of a drift. This will include geological factors such as weaker zones and natural cracks. The result of this project can be used to alter blasting designs and so reduce blasting damage in the rock. This will improve safety in tunnelling and reduce costs.
