Alimak raise climber :
The method of driving long raise with the
help of machine called. Alimak raise climber was introduced in 1957
the method of driving along raises with the help of a machine called Alimak raise. The method os based on rack and pinion drive with guide rail bolted to the hangwall by expansion. A cage for the workers and a working platform attached to it climb along the guide rail and drilling and charging of blast holes are carried out from this platform.
applicability:
-inclination: 40 to vertical
- length - depends on the size & capacity of machine.
Preparatory excavation - Space required for machine movement.
The Alimak raise climber consists of :-
1. A reel with air hose of provide compressed air to the twin air
motors causing travel of cage. The reel automatically winds upto
the hose when the raise climber descends and feed its during
ascent.
2. Guide the rails with the rock and pinion. The length of guide rails
1 or 2m. Some pieces are suitably curved for smooth profile. The
guide rails are bolted into rock bolts fitted in side of the raise.
3. The guide rails have recess to carry 2 compressed air tubes. 1
water tube and a telephone cable which is used for blasting.
4. The rock bolts are of expansion shell type recoverable spears
are provided to cover up the length between the rock bolt and
guide rail.
5. There is a cage that travel along the guide rail and carries the
driller and other screw to the face of the raise.
6. The working platform on the top of cage materials are
transported on the platform.
7. compressed air drive unit with air, motor for travel of the cage.
8. Protection canopy.
Working operation:
- preparatory excavation
- guide rail installation
- upward movement of ARC
- Drilling
- Charging
- Downward movement of ARC
- Blasting
- Ventilation: cleaning the fumes
- Mucking
- Upward movement of ARC
- Extension of guide rail
- Dressing
- Supports - side support by rock bolting.
Advantages:
1. The materials falls due to gravity in lower level.
2. Loading of material in lower level is quick.
3. Much of the time is saved by climber as workers are riding in it.
4. No ladder ways, pipes lines etc. are required.
5. Dressing is safe under canopy.
6. Platform is not damaged.
7. Cycle time is short.
8. It is quick method.
9. Suitable for vertical and inclined raise.
Disadvantages:
1. Guide rail damage
2. Initial expenditure high
3. Ventilation sluggish

Sir rail ko kaise support de rahe h or kise type ka support and materials?

[@AnitaDevi-kt3sf]

Good

[@kaluram9647]

👍❤️👍👍👍

[@simonmabanja3476]

Please use more English ,very informative videos thanks

[@proyeccionminera8504]

Excellent video! What program do you use for images and animations?

[@MININGMAFIA]

I am using PowerPoint and windows default video editor that's all. Sry this video sound is not in English Soo we introduce English videos . But you got all the respective notes in English in the video description.. #support and #subscribe..

[@MININGMAFIA]

Yeah! I am checking out your videos .. upcoming technological advancement taking place in Indian mines, I wish your videos gonna help m alot..

Sir is there any blast free technology for metal mines maintaining productivity of Mining equipment.

[@MININGMAFIA]

In coal there are numerous method whereas in metal, there are machines too but while mining for metal, hardness plays its role. So majority of metal mine uses Blasting as their prime technology. There are numerous variables need to be considered while planning, and metal means uncertainty, Grades changes, stratification changes, and alot more. So engineers now using 4.0 technology, doing all this operation in very effective, and controlled manner.. "more the volume of grade you mine, the more you control your prosperity of mine"

[@rakeshbobonga7094]

@@MININGMAFIA thank you sir it is really very informative 🙏

[@rakeshbobonga7094]

You mentioned about machines what are those?

[@MININGMAFIA]

CAT developed one of its kind Shearer for metal longwall, based on hammering and chisel action, attacking plane of weakness. But you know the geological aspects play imp role in longwall so there's alot restrictions too. Other are same as CMs. But metal mine is much more advanced in term of 4.0. The industry is moving towards autonomous operation. In India, Vedanta is a big player in initiating this advanced tech in cooperation with Sandvik. 4.0 brings revolution to mining, whatever you want, you get. Just need to apply right concept. It shifts our mine to a safer, very productive and efficient mine.
