Advantages and Applications of Rail Haulage Systems in

haulage from the underground draw point level, and the vertical haulage from the underground collection/deposit site to the sur-face processing plant and equipment above ground. Horizontal haulage is carried out using one or two of three haulage systems In bulk mining applications such as block cave mines the ore on the extraction level is passed to the haulage level through vertical ore passes.

Techniques in Underground Mining iloencyclopaedia

The Underground Mine The underground mine is a factory located in the bedrock inside the earth in which miners work to recover minerals hidden in the rock mass. They drill, charge and blast to access and recover the ore, i.e., rock containing a mix of minerals of which at least one can be processed into a product that can be sold at a profit.

Personnel and Material Transport underground COAL

Personnel and Material Transport. In mines with a drift where rubber tyred transport from surface is not practical, rail transport in the drift (with a haulage winder and not locomotives) is the norm, with transfer to rubber tyred transport at drift bottom. Most shaft mines also use rubber tyred transport from pit bottom.
