Shaft Design For A Mining Hoist

Mine Hoist Plant Design Fundamentals

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 also influence the maximum speed of the shaftmining engineering: Shaft Design,For a production shaft, design starts with determining the cross section or plan view of the shaft. The production shaft is designed to the minimum dimensions required to contain and guide the shaft conveyances, as well as provide space to place and access the utility lines. The design may include provision for a man-way compartment and ventilation duct(s). The conveyances may ride on rope,Shaft Sinking for Small-Scale Mining in Africa,Figure 1 depicts a small shaft used to mine tin in Rwanda utilising cage hoisting – whereby a mine car is filled with ore and is hoisted to surface. The paper looks at the practical aspect of artisanal shaft sinking utilising picks and shovels and contrasts this method to a shaft design

Shaft Sinking for Small-Scale Mining in Africa

contrasts this method to a shaft design suitable for small scale miners. Discussions are the design characteristic of a small scale shaft, shaft sinking and the timbering process, and methods to hoist broken rock from the shaft. The potential productivity of a small-scale shaft and the problems associated with small-scale shaft sinking are also examined.

How to Calculate the Size of a Mine Hoisting System

As an example, required to find size of rope necessary to hoist a total load of 5000 lbs. from a vertical shaft 1500 ft. deep. Assume, for a trial solution, that rope weighs 2 lbs. per ft. From equation 1, K=5000 lbs. X 2 +1500 X 2 lbs. + .01 X 8000 lbs. = 13,080 lbs., and ultimate strength of rope should be 7 X 13,080 =91,560 lbs., which would require a 1¼-inch- diameter flexible cast-steel,DESIGN OF MINE SHAFT ELEVATOR - mech-ing.com,Hoist elevators, Service elevators, Car elevators,,opencast mining would not be used for that deep excavations and that process is called “deep mining".
