The Alimak raising method consists of five steps, which together make up a cycle. The five steps are all dependent on the Raise Climber, which. ALIMAK INC. – Alimak Raise Climber. Operating height (m): . Operating width (m): Platform dimensions: m x m. Maximum length. In underground mining, a raise refers to a vertical or inclined excavation that leads from one level, or drift, to another. A raise may also extend to surface. There are four excavation methods for raises: Conventional or open raise; Long- hole or drop raise; Alimak · Raise boring.

Less Cost With less development, faster ore access, better ground control, and faster overall mining, it is easy to see how raise mining will cost less than regular open stoping. It is safest to take a few rings per blast, so that miss-holes or other blasting problems are accessible for correction. Ore passes and ventilation shafts totalling m.

Mining Equipment and Tools. Using curved guide rails the direction of travel can be changed at any time; forward, backward, or sideways.
With less development, faster ore access, better ground control, and faster overall mining, it is easy to see how raise mining will cost less than regular open stoping.

Drilling, loading and blasting are all performed from the platform of the Raise Climber, which is adapted to fit the precise rasie and shape of the raise. The rxise are timed to slash down, with the footwall holes often the last to fire. Blasting is triggered from a well-protected location at the bottom station. The holes are most often mechanically loaded with either ANFO or an emulsion explosive. Not exactly what you want?
The Alimak method yields high tonnage and low dilution results, while reducing mining costs. The platform can be any shape and size. Raise mining is a “longhole” method of bulk mining tabular narrow vein ore bodies. Regardless of the aimak of the shaft, the Raise Climber will end up at the right spot as its alignment in the shaft can be adjusted continuously according to laser readings.

Experience has shown that the stopes mined with a raise alimai tend to be more stable than regular longhole open stopes. Alimak machines are in operation throughout the world, developing ore passes, ventilation shafts, main shafts, and others, alimaj various inclinations and lengths.
There is often considerably less waste development with raise mining than with regular open stoping. Raise Mining Raise mining is a “longhole” method of bulk mining tabular narrow vein ore bodies.
The nest will be slashed out of the drawpoint backs if development is from the hangingwall side. It is also quite common that the production holes in the raise mining method are smaller than in regular stoping, which will spread the explosive energy more evenly.
The production drill sits in the middle flimber its work, cutting the drilled length in half.

The platform is adapted to fit the size and shape of the raise.
A Leader in Alimak Mining
The Alimak Mining Method Raise Climber Mining Conditions This type of mining is best suited to tabular narrow vein ore bodies with enough dip for gravity ore flow. The raise climber consists of a cage for the crew, with a working platform on top for roof scaling and drilling and charging of holes.
Faster Overall Extraction With better ground control, larger stopes can be taken. Raises must be driven big enough that a 2. The language you choose must correspond to the language of the term you have entered.
Where required, the stope hangingwall can be supported with deformed strand resin-grouted cable bolts in a regular pattern along the raise. More Selectivity The short drill holes make this method very effective in narrow veins.
Drawpoints can be driven from either footwall or hangingwall, depending on how the ore zone is accessed. Writing tools A collection of writing tools that cover the many facets of English and French grammar, style and usage. The machine, equipped with rack-and-pinion drive, travels along a guide rail and monorail with pinion rack, which are bolted to the hangingwall by expansion bolts.
There are several explanations, which include: With some exceptions, production blasting can start in the quarter after raise development starts. Drilling, which is done from the platform of the Raise Climber.
Boxholes, raises at degrees and ore passes. This alkmak very cost effective as the raise is centred in the stope, which concentrates the support where it is needed most. Better Ground Control Cables can be installed right up the middle of the hangingwall, where they will do the most good. This advantage is easily visualized if one imagines the hangingwall as a fractured beam or plate.
Manroc routinely applies rigorous maintenance programs and checks on all our Alimak equipment ensuring the safety of all individuals. Drawpoints and Climber Nest: The sub-horizontal production drill hole direction allows the use of the undercut as a slot and because of the increased stope height, there will be significantly fewer of these than there would be slots required for regular open stoping in the same area.
FAQ Frequently asked questions Display options. These drifts are also driven from the shaft or existing development but, unless there is another lift, they often need only be large enough for the movement of supplies. A collection of writing tools that cover the many facets of English and French grammar, style and usage. Rase drifts are driven from the shaft or established mining areas to the new ore zone.
