depends on its design, therefore proper and accu rate design of a hoist is essential. In this rese arch, the design of the comp on ents making up the hoist was done t hrough literature survey.
Jun 06, 2018 · As a key component of a mine hoist system, the mainshaft device bears most of the bending moment and torque. Thus, it is important to quantify the performance of the mainshaft device and ensure the reliability of the device. The paper aims to investigate the impact of uncertain structural parameters on the reliability of the mainshaft device. The probabilistic optimal design is performed ...
The hoisting system is a crucial part of many mining operations, specifically those underground mines that feature a vertical shaft entry for both personnel and material haulage. There are two main types of hoisting systems, Drums and Friction.
Superior mine hoist reliability. Mine hoisting systems comprise five major components: hoists, conveyances, wire ropes, shafts, and head frames. Each of these components requires extensive design considerations. Increasingly, electric motors are replacing diesel motors and eddycurrent motors for operation of mine hoists.
Oct 02, 2018 · The mining industry uses a lot of wire rope, not only for hoists for shafts and slopes, but also for elevators, cranes, draglines, and haulage cables. This report is limited to a discussion of the kinds of wire ropes used for hoists in coal mines and in metalnonmetal mines.
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.
Oct 01, 2015 · Mine hoists are responsible for the safe transport of people and material underground so they need to be 100 per cent reliable. Keeping the hoist up and running requires – more than any other item of mining equipment – the skills of two diverse engineering teams: .
Koepe hoists are practicable down to about 2,000m. Blair hoists can go deeper; and for the deepest lifts of all, doubledrums are used. So we begin to get a feel for the complexity of minelifting design; but there is much more. Which system you use, and which is most efficient, will depend on the depth, the needed capacity, the loads.
The switchback inset handles mine cars on two rails on one side of the shaft, saving space and material costs; Safe passage for mine personnel onto and off the hoist; Turnkey solutions and customized design; Onsite service and sparepart supply; Typical appliions. Underground mining; Shaft hoisting
General. This document specifies the design loads and the design procedures for the design of rope guides and rubbing ropes used for guiding conveyances and preventing collisions in vertical mine shafts for permanent operations. This standard covers personnel and material hoisting, as .
12ft Hoist, ASEA Single Drum Hoist, 12ft x Mine Hoist, Type HTDE144 INCH, Serial # 329, ASEA 2,100 / 4,080 kW, 1000 VDC Drive Hoist Motor, 65,000lbs Line Pull, variable speed up to 2,000 fpm, Direct Drive, 3,000 Foot Depth, '' rope diameter, 66,000 lbs maximum static rope stress, Disk Brakes with four brake stands one disc on each ...
The system reliability evaluation of the main shaft device is then calculated. A numerical example of a main shaft device is illustrated to validate the appliion of the proposed method. The method proposed in this study can be provided for the analysis and design of the main shaft device of deep well hoist as a necessary theoretical basis.
FL Mine Shaft Systems has over 100 years of design and installation experience, having installed over 500 hoist systems. We have both designed and manufactured more Blair MultiRope hoists than any other hoist supplier. We are also the first company to successfully design and deliver a hoist with a winding depth of 3150 meters.
Dec 10, 2008 · (HANCOCK, Michigan) – A fall at the Quincy Mine Hoist Shaft Saturday proved fatal for a volunteer at the shaft, who was also an associate professor of geology at Michigan Technological University. According to a written statement from the Houghton County Sheriff's Office, William J. Gregg, 60, was attempting to install emergency ladders in ...
Elements. of Shaft Hoisting Systems, • The depth capacity of drum hoists can be extended using two ropes per conveyance (Blair hoist) • Blair hoists can exceed the depth of single rope or friction hoists • Friction hoists with multiple ropes a higher payload and have higher output (tons per hour) than drum hoists within a range ...
Design of a gold mine shaft hoisting system. ... A mine hoist for hauling gold ore from the 252m level of an underground mine to the 101m level was designed with the objective of cutting ore ...
A separate 80' x 158' structure was erected to cover the hoist house and the electrical building on the property. The flexibility of the Sprung structure design made Sprung the right choice for this mine. This mine will leapfrog the structures from shaft to shaft.
