AutoStem's 2021 New Generation formulation means unmatched performance with more power than conventional packaged explosives*,yet with greater than a 95% reduction in shock (and vibration) relative to conventional explosives.
Unlike conventional explosives, AutoStem Gen 3 requires no stemming, no explosive accessories and a 50m clearing area. Only one action is required, disarming the safety and you are ready to blast. As a result, AutoStem™ can be used with minimal user risk. AutoStem™ 3 is a revolutionary disruptive innovation in explosive technology.

SUMMARY TECHNICAL INFORMATION
AutoStem products were designed to blast out the hardest of rock conditions with an inherent dual stemming capability and higher energy rating than conventional explosives. Autostem can be used as a replacement of high explosives with or without explosive accessories depending on whether sequential firing (timed firing) is required. A flexible cartridge range offers a rock breaking solution for both primary and secondary blasting applications in any environment. The novel safety switch technology ensures safe transporting, storing and handling and the waterproof casing prohibits water contamination during the charging process. Due to the non detonating characteristic of the cartridge, impact or vibration on surrounding strata, property and infrastructure is low and therefore can be used in proximity.
THE INNOVATIVE ROCK BREAKING SOLUTIONS PROVEN OPTIMUM RESULTS WORLDWIDE

AUTOSTEM Vs. CONVENTIONAL EXPLOSIVES
66% reduction in vibration using Gen III
4.8kg of AutoStem used versus 10.0kg of conventional packaged explosives for a 1.2m advance, 90% reduction in dust, and vibration at 6m, 12m and 18m markedly reduced. Immediate re-entry possible with no toxic gas concentration
Breaking rock with conventional high explosives has a high transportation, storage, environmental and handling risk and mitigating such risk more especially the risk of self ignition is of primary concern. The innovative AutoStem™ Technology reduces this risk exponentially bringing all round improvement in safety. Shutting down and evacuating a site for blasting is not necessary. AutoStem™ allows for a minimal clearance of only 50 meters and can also be used near to communities, infrastructure & buildings thus reducing the hazard and risk of damage to people or property.
AutoStem rock breaking cartridges are safer and more powerful than the next best packaged explosive at 5,121 j/g
