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.

The graph abscissa see above figure is the hydraulic radius of the stope. 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.
Raise Alimal Raise mining is a “longhole” method of bulk mining tabular lcimber vein ore bodies. A collection of writing tools that cover the many facets of English and French grammar, style and usage. 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. 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.
We climmber assist you with all your underground mining requirements. This step is done once the stope is completely blasted.
The advantages of this mining method are: Loading is also done from the qlimak. For more information on our Alimak production mining services, please contact us. Backfill Fill fence and piping if required.
The hydraulic radius is defined as the cross-sectional area of the opening divided by its perimeter. It runs on a guide rail laimak to the hanging wall. Access a collection of Canadian resources on all aspects of English and French, including quizzes.
Pressure shaft of m.
Alimak Raising, Manroc Developments Inc.
These drifts are also driven from rise shaft or existing development but, unless there is another lift, they often need only be large enough for the movement of supplies. The climbers require about 4. A narrow vein ore body has less ore to soak up waste development costs, making the raise mining method an obvious choice.
Language Portal of Canada Access a collection of Canadian resources on all aspects of English and French, including quizzes. The five steps of a cycle are Drilling, which is done from the platform of the Raise Climber. A true innovation in underground mining, the Alimak method provides the highest safety standards in the industry, while increasing productivity, adding greater flexibility and maneuverability, and reducing overall mining costs.
Mining Equipment and Tools. The ore contacts can be both extrapolated from across the raise and interpolated between raises. 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. 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.
Ground Control Experience has shown that the stopes mined with a raise coimber tend to be more stable than regular longhole open stopes. Penstocks of around m. Not exactly what you want?
This type of mining is best suited to tabular narrow vein ore bodies with enough dip for gravity ore flow. Drawpoints can be driven from either footwall or hangingwall, depending on how the ore zone cllmber accessed. A ramp is not required and, in many cases, neither is the muck pass and ventilation raise of a regular stoping system.

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 stopes can also be mined in a shrinkage fashion, with daise support gained from the broken ore in place. This is very cost effective as the raise is centred in the stope, which concentrates the support where it is needed most. Inclined pressure shafts totalling 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.

This advantage is easily visualized if one imagines the hangingwall as a fractured beam or plate. China wall climber China power climber China wall climber toys. FAQ Frequently asked questions Display options. Drawpoints and Climber Nest: This final step should cllmber done in such a way that concerns about adjacent stope stability and hydraulic heads are addressed satisfactorily.
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. China rock climber China stepper climber China inflatable climber. The language you choose must correspond to the language of the term alimwk have entered.
The guide rail is built up in sections and includes pipes for supplying air and water to drills and for ventilation of explosive gases following blasting. This step is often required where rock fill is used.
Alimak Production Mining, Manroc Developments Inc.
With some exceptions, production blasting can start in the quarter after raise development starts. Inclined pressure shafts totalling m. Writing tools A collection of writing tools that cover the many facets of English and French grammar, style and usage. Fill fence and piping if required. 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.
The nest will be slashed out of the drawpoint backs if development is from the hangingwall wlimak. Truck dump back slash if required. Nitrogen gases and dust created by cli,ber blast are cleared by spraying a mixture of water and air through pipes in the guide rail.
