ALIMAK MINING PDF

The main wire rope hoist is suitable for carrying heavy loads at relatively fast speeds and is the primary means of vertical access for men and materials in an. Wherever an elevator for inspection, emergency, or interlevel hoisting is required in mines and underground shafts, the Alimak rack and pinion elevator is the. Raise climbing, widely known as the Alimak mining method after the company that introduced it, is a variation on longhole stoping developed.

The elevator can be installed easily, and the cost is moderate because no machine room is needed.

This allows the drill planning to be done before the production drill is set almak in the minning. 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. Cable bolting provides better ground support from its position in the central hangingwall of the stope, and the broken ore adds support by putting outward pressure on raise walls.

The bulk of the waste development required with this method is the ore zone access and the raise climber nests. The mmining nests are always in the hangingwall. Most of the rest of the development is in ore see centerfold.

A Leader in Alimak Mining

Greg Dipple of UBC has discovered that certain mine tailings can be used for carbon sequestration, and the implications could be enormous.

We are pleased to provide lateral mine development as a part of our comprehensive range of underground mining services.

All packed and ready to go Eavan Moore. This advantage is easily visualized if one imagines the hangingwall as a fractured beam or plate. 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.

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.

Switching to a new drill, they drive cable bolts up the centre of the raise, grout them in place and drill production holes. Teck installs first production-scale machine learning system Machine learning predicts when trucks will need maintenance at Fording River coal mine. Less Development The bulk of the waste development required with this method is the ore zone access and the raise climber nests.

There is often considerably less waste development with raise mining than with regular open stoping. Faster Access to Undeveloped Ore Once the climber nests are established, ore starts to flow. Stopes can be as little as 3 feet thick, or even less in ideal circumstances. Eliminating the intervening levels cuts out a good chunk of lateral development time and spending. The change in geometry and improvement in ground support allows stope heights in the order of 75 to metres, eliminating many sub-levels and their associated development.

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 Strike length was also reduced from 15 to 14 metres after problems with hangingwall caving and dilution.

Manroc Developments is a full service mine engineering company employing a highly qualified team of mining engineers and associates with extensive experience in underground mining. The Alimak elevator is the perfect solution for underground as well as aboveground mining industry applications, such as pelletising plants, smelters, concentrators, and other ore processing plants.

Backfill Fill fence and piping if required. The ore contacts can be both extrapolated from across the raise and interpolated between raises.

The Saskatoon-based gold miner had increased its year-to-date gold production by 63 per cent overthanks in part to a successful implementation of the Alimak mining method at its Seabee gold mine in Saskatchewan. Specialized Services Professional Mine Engineering Manroc Developments is a full service mine engineering company employing a highly qualified team of mining engineers and associates with extensive experience in underground mining.

This improves drill accuracy which, in conjunction with the better ground control, reduces dilution substantially. The method works best if the ore boundaries can be interpolated between adjacent raises.

Once the climber nests are established, ore starts to flow. A narrow vein ore body allimak less ore to soak up waste development costs, making the raise mining method an obvious choice.

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.

Manroc, Williams and Orica Ltd. The main wire rope hoist is suitable for carrying heavy loads at relatively fast speeds and is the primary means of vertical access for men and materials in an underground mine.

Miing, we incorporate both conventional and mechanized production mining techniques, as determined by the individual requirements and overall complexity of each site.

Overall costs moning lower, but the method also costs more to run, which could deter some but does not faze its proponents.

Raise Climber Mining Method Details The raise climber mining method will miing be comprised of the following steps: The broken ore often compacts slightly, resulting an effective swell of about one third its unbroken volume. They blast the first few metres of the raise and then install a climber running on a curved rail from the nest into the raise.
