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.

Primary and Secondary Blasting System | Integrates any Centralized Blasting System | Sequential Ignition | Continuous Blasting Cycle | Self-Stemming | Non-Detonating | No Airblast | Low Vibration | No Overbreak  | Controlled Fly Rock | Decreased Danger Area | No Noxious Emissions | No Evacuation Of Personal and Equipment Necessary | No Explosive Registered Delivery Vehicle Required

AUTOSTEM BENEFITS

Power_edited.png

Power

AutoStem delivers twice the power than conventional high explosives so less is required.

Accessories_edited.png

Accessories

AutoStem products do not require expensive accessories such as detonators, which also does away with the requirement for strict stock control and inventory of these products.

Manufacturing_edited.png

Manufacturing

AutoStem production processes are more simplified, greener and less expensive.

Autostem%20Technology_edited.png

Transportation

AutoStem does not require special vehicles with security escorts for transportation, and storage is simplified.

Safety_edited.png

Safety

Using AutoStem does not require clearing of equipment and personnel for more than 50m and in a mining environment re-entry is immediate.

Storage_edited.png

Storage

Shelf-life of AutoStem is years, so if not used immediately it is not wasted – explosive are months.

AUTOSTEM DELIVERS MORE POWER

THAN CONVENTIONAL HIGH EXPLOSIVES

SUMMARY TECHNICAL INFORMATION

Energy_edited.png

Energy content

More powerful than the next best packaged explosive at 5,121 j/g energy capacity

Speed%20of%20Deflagration_edited.png

Speed of deflagration

340 m/s – Ensuring minimal vibration impact to surrounding environment

Pressure_edited.png

Pressure

500 MPa – With reaction runaway, AutoStem Cartridges reach maximum pressure within milliseconds sufficient to break out the hardest rock

Density

1.1 g/cm3 – Highest packing and mix density makes Gen III Cartridges the most powerful blasting cartridge available worldwide

Vibration_edited.png

Vibration

PPV reduction relative to conventional explosives by up to 90% (depending on cartridge size, rock competency and application type)

Water_edited.png

Water resistant

Water resistant as a standard to a depth of 50m (6 bar)

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 SMART BLASTING SOLUTION PROVEN OPTIMUM RESULTS WORLDWIDE

AUTOSTEM Vs. CONVENTIONAL EXPLOSIVES

Picture1.png

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

autostem_vs_conventional.gif

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
