With the fluctuating prices of industrial explosives and the increasing depth of open-pit mines, cost control has become a top priority for mining executives. One of the most effective yet underutilized strategies for reducing operational costs is "Air Decking" technology.
Air decking involves placing an intentional air gap within the explosive column using specialized spacers. This simple modification changes the physics of the blast. The air gap acts as a cushion, extending the duration of the gas pressure acting on the rock borehole walls. The result is improved rock fragmentation and reduced ground vibration, all while using significantly less explosive material—often saving between 15% to 30% on explosive costs per blast.
