Perhaps the most consequential area of potential improvement for the mining industry – subsurface evaluation during drill and blast operations – has seen only limited innovation, if any. Due to the tempo of drill and blast activities, historically there has not been sufficient time to adequately characterize the bench prior to blasting.
