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. let’s 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 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.
