    Abstract. In some mining operations, one of the most important roles played by the geologist is the supervision of grade control. In an open-pit operation, this involves the sampling of blast-hole cuttings produced by down-the-hole hammer drills and the classification of bench reserves into ore, low grade or waste material, or into various metallurgical types.

    Because your grade control process has to account for blast movement. Blast conditions are unique—the blast design, explosive or firing change with every blast. And the impact of changes in the rock mass or voids is unpredictable. BMT’s research, over 13 years, shows the variability of blast movement means it is not possible to predict or model with sufficient accuracy for grade control,
