Mine Haulage. Transportation of coal inside the mine can be described by two types of haulage locomotives. The first being a main haulage locomotive, the second is a gathering locomotive. Lets look at the properties of each locomotive. 1. Main Haulage Locomotives. Locomotives of this type are the heaviest of those used anywhere in the mine.

Haulage An Overview Sciencedirect Topics

In underground mines, especially large ones, a distinction needs to be made between main haulage, intermediate or secondary haulage, and face haulage. Face haulage, or transportation of the broken rock away from the face, is frequently accomplished by shuttle cars Fig. 17 or by underground mine trucks, although, as mentioned earlier, load ...
