In handling earth, aggregate rock, ore, coal and other materials, trucks serve one purpose. They are hauling units which, because of their high speed when operating on suitable roads, have high capacities and provide relatively low hauling costs.They provide a high degree of flexibility as their number may be decreased or increased easily to permit modifications in the total hauling capacity of a fleet.In cyclic operations, the two principal operations are loading and haulage with hoisting as a third optional. In continuous operations, where machines combine the breakage and handling functions, cutting, drilling and blasting are eliminated and extraction and loading are performed in a single operation or function (excavation), e.g. the bucket wheel excavator, auger, highwall mines, continuous miner or the boring machine.Materials handling in modern mechanized mining is equipment oriented. Unit operations are characterized by, and sometimes identified with, an equipment that performs them. Thus the field terminology refers to a mining shovel, stripping dragline or the coal loader. From time to time the mining engineer is faced with the necessity to make a haulage study to determine not only the most suitable method of hauling materials, but also the most effective and economical type of equipment used for the operation. Key words: truck haulage, material handling, mining shovel
