Alimak Production
A true innovation in underground mining, the Alimak Mining Method provides high safety standards while increasing productivity, adding greater flexibility and reducing overall mining costs.
These drifts are driven from the shaft or established mining areas to the new ore zone.
Raises must be large enough to accommodate a 2.4 metre drill, roughly 2.7 x 2.7 metres horizontally.
Drill holes extend to just less than half way to the next raise and are oriented slightly down from horizontal.
The holes are most often mechanically loaded with either ANFO or an emulsion explosive.
Normally, most of the ore remains in the stope while blasting, as it supports the walls during successive blasts.
Once blasting is complete, the stope is mucked clean and often backfilled.
Over the years, we have been perfecting a method which enables us to blast a stope in its entirety.
