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

Pressure

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

Density

1.5 g/cm3 – Highest packing and mix density makes Gen III Cartridges the most powerful rock breaking cartridge available worldwide

Vibration

PPV of <2mm/s at 6m – minimal vibration caused, due to low delfagration speed during runaway (as measured by Peak Particle Velocity)

Water resistant

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

66% reduction in vibration using Gen III

4.8kg of AutoStem used versus 10.0kg of conventional packaged propellant based rock breaking cartridge 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
