Abstract

Method performed by a system for determining one or more parameters to use for drilling a subsequent hole in a rock to approach a target, wherein the target is related to a subsequent blasting of the rock. The system drills a first hole in the rock. The system collects data relating to the rock, which data is collected from a drill rig during drilling of a first hole in the rock. The system determines at least one drilling parameter, based on the collected data of the rock. The system drills a second hole in the rock using the at least one drilling parameter, thereby approaching the target.
