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.

A collection of writing tools that cover the many facets of English and French grammar, style and usage. This should also contribute to a more stable hangingwall. Drilling, which is done from the platform of the Raise Climber. This step is done once the stope is completely blasted. We are your preferred underground mining professionals. 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.

Fewer, larger cclimber can be taken quicker because there are fewer cycles, i.

There are several explanations, which include:. Drill holes extend to just less than half way to the next raise and are oriented slightly down from horizontal.

Our full team of experienced Raise Miners, Supervisors and Managers, ensure your project is carried out meticulously, while meeting all budget and time constraints.

Inclined pressure shafts totalling m. 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. Experience has shown that raises from 75 to metres length are the most economical. For more information on Manroc’s Alimak raising services, please contact us. Drawpoints and Climber Nest: Raise Climber Mining Method Details The raise climber mining method will generally be comprised of the following steps: There are several explanations, which include: 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.


Specifications HS CODE Features 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. 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 bulk of the waste development required with this method is the ore zone access and the raise climber nests.

In theory, and if properly cabled, the foliated hangingwall could be approximated as a laminate beam by the Voussoir approach, as described by Hutchinson and Diederichs The climbers require about 4. raie

China rause climber China power climber China wall climber toys. China climber 1 China steel climber China climber stepper. Pressure shafts totalling m. Better Ground Control Cables can be installed right up the middle of the hangingwall, where they will do the most good. This step is often required where rock fill is used.

As a result, raise production of only a few hundred metres per year becomes profitable with the Raise Climber. The holes are most often mechanically loaded with either ANFO or an emulsion explosive. The platform is adapted to fit the size and shape of the raise. Intuitively, geometry favors raise climber mining, in that access is gained to the centre of the stope hangingwall where the ground support does the most good.

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. Alimak machines are in operation throughout the world, developing ore passes, ventilation shafts, main shafts, and others, at various inclinations and lengths.


Anglo Gold, South Africa: The stopes can also be mined in a shrinkage fashion, with added support gained from the broken ore in place. China rock climber China stepper climber China inflatable climber.

Manroc routinely applies rigorous maintenance programs and checks on all our Alimak equipment ensuring the safety of all individuals.

A narrow vein ore body has less ore to soak up waste development costs, making the raise mining method an obvious choice. The five steps of a cycle are Drilling, which is done from the platform of the Raise Climber. 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.

This is very cost effective as the raise is centred in the stope, which concentrates the support where it is needed most. This improves drill accuracy which, in conjunction with the better ground control, reduces dilution substantially.

This allows the drill planning to climbee done before the production drill is set up in the raise.

Since its introduction, the Raise Climber has been developed and improved into what is now the 6th generation, the Alimak RCM-series, enabling fast, mechanized drilling of long, inclined shafts and improved working environment. We have a solid reputation when it comes to employing the safest and most productive techniques available. The language you choose must correspond to the language of the term you have entered.

With better ground control, larger stopes can be taken. This advantage is easily visualized if one imagines the hangingwall as a fractured beam or plate. Most of the rest of the development is in ore see centerfold. How It Works The Alimak method raises between levels in a safe and effective manner.
