Underground mines have changed their operation systems in accordance with the evolution of equipment, the system and method of mining. Transport is also of critical importance in underground mines as is the mining operation itself. The underground transport system of ores, materials, equipment and persons has been developed from

Haulage alone plays a major role. Current haulage techniques are a significant cost driver, which account for between 15 and 30% of the overall capital investment (capex) in a mine and are an increasingly part of the operating costs (opex). The paper introduces a simulation tool of main haulage system in underground mining.
resulted a change in mine haulage systems. Ramp haulage system, if applicable, has become a new alternative to the shaft system for some underground operations. As a result, a number of mines have adopted ramp haulage system for transporting ore (Nilson1). For example, twothirds of Australia’s underground mines have chosen a ramptruck
Conveyor systems have come into common use in coal mines during the past decade. As this is written, belt conveyors are beginning to make their appearance in metal mines as a part of the underground transportation system, and an increasing number probably will be installed during the next few years. Locomotive Haulage

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on …
