Jan 01, 2019· PRELIMINARY DESIGN INFORMATION Before any engineering commences, the following information needs to be obtained to allow the preliminary sizing of the hoist plant equipment: • Shaft depth: The shaft depth will influence the hoist rope selection based on the material and personnel loads anticipated for the mine design. The shaft depth will ...
The mine cage and the skips are lowered into the mine when a steel cable unwinds from the winch. The mine cage and skips are raised when the steel cable winds up again. Part 2: The sheave wheel is a pulley wheel that sits above the mine shaft. The hoist cable passes over the sheave wheel and then down the shaft of the mine.
that process is called "deep mining". When it comes to design of a mine shaft, there are two options: circular shafts and horizontal shafts (Figure 1, Figure 2). Circular shaft is the most commonly used one. If the shaft should be deep and shaft diameter is supposed to be more than 4.5 meters, circular shafts are the best choice.

Sockets are used on a variety of mining rope applications, including hoist, balance, guide and sinking ropes. The socket attachment offers a safe, economical connection and can be installed with a quick and efficient wirelock resin. This socket may be more desirable than the OS design where headroom is an issue, as it may eliminate one rope ...

Timberland provides years of leadership in the design and manufacture of equipment for ongoing work in mining and shaft projects. We offer a complete range of custom hoists including production hoists, service hoists, personnel hoists and emergency egress hoists.
Underwind and overwind protection system concepts for mine hoist shafts were developed in conjunction with and for the Safety in Mines Research Advisory Committee (SIMRAC). End-of-wind operation of mine hoists is the most hazardous aspect of mine hoisting, carrying the highest risk of loss of life, injuries to workers and loss of production.
