Dynamic energy control for coal geology Tailor energy profiles to match coal seam variability and improve blast outcomes.

Traditional bulk explosives systems rely on density-based design—meaning the explosive’s performance is determined by its physical density. This approach limits flexibility because each product has a fixed energy profile, requiring multiple products or complex decking to manage variations in geology and hole conditions. 4D™ introduces energy-based design. Instead of focusing on density, 4D™ measures and controls the energy delivered into the blasthole. This shift enables engineers to tailor blast energy precisely to match geology and desired outcomes, without changing products. Key Differences Conventional systems: Fixed density per product Limited ability to adjust energy within or between holes Requires multiple products for different conditions 4D™ systems: Energy—not density—drives blast performance Adjust energy from hole to hole  Delivers the industry’s widest Relative Bulk Strength (RBS) range using a single emulsion and gasser combination Simplifies blast design and improves consistency
