Considering that hoist systems have heavy payloads travelling at high speeds, any failure is likely to have fatal and/or expensive consequences. Mine hoists, however, are large constructs spread over massive areas and maintenance time windows are limited.
The shafts did not have "dog legs" (horizontal off-sets) in them due to their intended purpose (hoisting) and/or method of construction (vertical sinking). Larger mines requiring higher airflows had a number of unequipped surface intake and exhaust shafts due to the limited air-carrying capacity of a …

A long shaft motor is the minimum required, and the extra long 25" shaft motors are the best. A remote control can also help make operation very easy with aft cabin models. With weight being important, try to choose the lightest possible outboard. There are a number of specialist 'Sail Boat' motors

Answer: A better question would be what aren't the problems associated with deep shaft mining. I guess if one were to rank these by seriousness and cost inefficiency, it would go something like this…. First the labor force is an extremely small pool of highly-skilled professionals who do extreme...
§ 45.2-742. (Effective October 1, 2021) Operations of hoisting equipment. A. The speed of the cage, car, or trip in a shaft or slope or on a surface incline shall not exceed 1,000 feet per minute when a miner is being hoisted or lowered. B. When moving the platform or work deck, every miner traveling thereon shall have a safety belt secured. C.

shafts, (where no personnel are exposed), there is a practical limit to tolerable air velocity in main intakes (shafts and declines) and main development openings where persons travel and work. Dust generation is one problem deriving from intake velocities in excess of 6m/sec.
§ 57.19061 Maximum hoisting speeds. The safe speed for hoisting persons shall be determined for each shaft, and this speed shall not be exceeded. Persons shall not be hoisted at a speed faster than 2,500 feet per minute, except in an emergency.
Observe speed limits and ensure you can make a safe stop at any time. Avoid rapid acceleration, deceleration and quick turns. Drive carefully on wet or slippery surfaces or when pedestrians are near. Reduce speed when making a turn.
Shaft construction utilising the blind sink technique involves repetitive work cycles of drilling, blasting, extracting earth and material, installing ground support, formwork and concreting sequences to construct a shaft. The cycles are repeated until the shaft reaches the intended depth. Refer page 9.
