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.

Alimak Raising, Manroc Developments Inc.
With less development, faster ore access, better ground control, and faster overall mining, it is easy to see how flimber mining will cost less than regular open stoping. With better ground control, larger stopes can be taken. This type of mining is best suited to tabular narrow vein ore bodies with enough dip for gravity ore flow. The Raise Climber operates with almost surgical precision.
The platform is adapted to fit the size climbsr shape of the raise. This improves drill accuracy which, in conjunction with the better ground control, reduces dilution substantially. The main ore access is gained by driving a raise up dip along the centre of the stope hangingwall, rather than from over and under-cuts driven along strike, as is done with regular open stoping.

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.
This should also contribute to a more stable hangingwall.

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. There is often considerably less waste development with raise mining than with regular open stoping. The climbers require about 4. Pressure shafts totalling m.
The drifts are commonly sized to accommodate the large scooptrams used for production mucking and are often driven with jumbos. Faster Access to Undeveloped Ore Once the climber nests are established, ore starts to flow.
Alimak Raise Climbers and shaft enlarging equipment are available for underground mining, civil engineering and hydro-electric power generation as well as for operating as inter-level service lifts. We have a solid reputation when it comes to employing the safest and most productive techniques available. Experience has shown that raises from 75 to metres length are the most economical.

The climber nests are always in the hangingwall.
Language Portal of Canada Access a collection of Canadian resources on all aspects of English and French, including quizzes. The raise mining method takes advantage of this concept because, even though the hangingwall climbef only supported up its centre, the resulting two unsupported strips are long and narrow and are more likely to be self-supporting.
There are several explanations, which include:. Contact Us For more information on Manroc’s Alimak raising services, please contact us.
Alimak machines are in operation throughout the world, developing ore passes, ventilation shafts, main shafts, and others, at various inclinations and lengths. Truck dump back slash if required.
This step is done once the stope is completely blasted. Boxholes, raises at degrees and ore passes. It is better if the ore body is continuous over several hundred feet vertically. The holes are most often mechanically loaded with either ANFO or an emulsion explosive. The graph ordinate is an estimate of the rock stability and includes factors for block size, joint surface condition, rock strength, joint orientation and the effect of gravity.
Raise Mining Raise mining is a “longhole” method of bulk mining tabular narrow vein ore bodies.

China climber 1 China steel climber China climber stepper. Drilling, loading and blasting are all performed from the platform of the Raise Climber, which is adapted to fit the precise dimensions and shape of the raise. When the air has been cleared the crew can ascend in the Raise Climber to the face, scale and install a new guide rail section, all under protection of the safety roof.
Furthermore, the Alimak Raise Climber implements a rack and pinion rail, designed to carry air and water for increased ventilation.

The Raise Climber serves both as working platform and as a means of transport up to the work face. The stopes can also be mined in a shrinkage fashion, with added support gained from the broken ore in place. It faise often best to leave ore in the stopes while blasting because of the support it gives.
