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.

We are your preferred underground mining professionals. These drifts are driven from the shaft or established mining areas to the new ore zone.
The down dip helps the toes break to the stope wall. Regardless of the length 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. Fill fence and piping if xlimber.
Fewer, larger stopes can be taken quicker because there are fewer cycles, i. Backfill Fill fence and clomber if required. After the raise is driven it often must be rehabilitated, subject to ground conditions, for the safety of production crews.

The ore contacts can be both extrapolated from across the cpimber and interpolated between raises. For more information on Manroc’s Alimak raising services, please contact us. Language Portal of Canada Access a collection of Canadian resources on all aspects of English and French, including quizzes. Experience has shown that raises from 75 to metres length are the most economical. Nitrogen gases and dust created by the blast are cleared by spraying a mixture of water and air through pipes in the guide rail.
Drill holes extend to just less than half way to the next raise and are oriented slightly down from horizontal. Gallery Click on the photos below for a larger view: 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 holes are most cliimber mechanically rzise with either ANFO or an emulsion explosive.
The production drill holes are oriented slightly down from along strike, which is also roughly perpendicular to that found in the regular open stoping method. Formation of this beam is helped by the ability to cablebolt up the centre of the hangingwall as well as on top and bottom sills.

Anglo Gold, South Africa: Stopes can be as little as 3 feet thick, or even less in ideal circumstances. Ground support follows development and production drilling follows right after that. Alimak machines are in operation throughout the world, developing ore passes, ventilation shafts, main shafts, and others, at various inclinations and lengths. The platform is adapted to fit the size and shape of the raise.
The broken ore often compacts slightly, resulting an effective swell of about one third its unbroken volume. Blasting is triggered from a well-protected location at the bottom station. It is better if the ore body is continuous over several hundred feet vertically.
The nest will be slashed out of the drawpoint backs if development is from the hangingwall side. 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. The method works best if the ore boundaries can be interpolated between adjacent raises.
Aljmak climbers require about 4. Drilling, which is done from the platform of the Raise Climber. In which subject field?
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. Drawpoints and Climber Nest: Manroc routinely applies rigorous maintenance programs and checks on all our Alimak equipment ensuring the safety of all individuals.
It is safest to take a few rings per blast, so that miss-holes or other blasting problems are accessible for correction.

Inclined pressure shafts totalling m. Mining Equipment and Tools . Less Dilution The production drill sits in the middle of its work, cutting the drilled length in half. The Raise Climber operates with almost surgical precision.
