Rail Haulage Transportation

On a worldwide basis trackbound transportation is on the decline. As mining operations progress from open cast operations to underground operations, most utilise mechanised equipment. However, in South Africa hard rock mines, only a small percentage (¦10 per cent) of the production can be generated by mechanised methods and therefore trackbound mining methods will remain the dominant means to transport ore. In the Australian context there may be occasions where the nature of the orebody would dictate the use of rail transportation with the ore being transported from drawpoints by means of locomotives and hoppers. This paper focuses on horizontal rail haulage systems from the stope loading boxes to the shaft station area and will be largely based on South African experience. It is intended that this document will provide a practical guideline for mine designers and planners during the design process. The paper looks at trackbound transport systems and evaluates such items as construction and management of an underground rail haulage system. Current transportation systems for personnel, material and rock transportation are evaluated, gaps in technology highlighted, and recommendations made.
