Consumable materials used in mines are often transported to the working areas down shallow angle decline shafts, typically at anywhere between 10 and 30 to the horizontal. The winding equipment is usually a relatively small single-drum winder and the material is transported in one or more cars, running on rails in the decline. The winding rope is attached directly to the cars, which are mechanically coupled together. For small rock hoisting declines, the cars are replaced with hoppers or skips._x000D_
The winder is normally of basic design, fitted with only the minimum required safety devices and very elementary brake control. Since these winders are not licensed' and are usually located in remote areas, the standard of maintenance on the installations is often poor, leading to frequent accidents, resulting in runaways, derailments and broken ropes. These problems can be overcome easily with the application of the rope haulage principle._x000D_
When large volumes of ore have to be transported to surface, belt conveyors are used on shallow angle inclines, or high-capacity friction winders are used in vertical shafts. Conveyors are limited to inclines no steeper than 14 and vertical shafts with large friction or drum type winders are extremely capital-intensive. Rope haulage systems can be used on decline shafts where the inclination is too steep for belt conveyors and too shallow for conventional drum winders. Rope haulage systems also offer a variety of safety, technical and cost advantages over other winding and transport systems._x000D_
This paper describes the adaptation of the rope haulage principle to modern requirements and, combined with 21st century electronic technology, explains how the principle can be used as an efficient, safe and practical solution to some problems associated with the transport of materials, personnel and ore in mines._x000D_
The authors describe the designs, methods of operation, safety aspects, automated control, loading and unloading facilities of modern rope haulage systems used for transporting personnel, material and ore. This paper considers a variety of systems already designed for different applications, from small material-only installations to multi-purpose and large rock-hoisting systems with payloads as much as 180 t. It also describes in more detail, a material transporting system recently commissioned in South Africa.
