Abstract: The combined tasks of excavation and hauling are the foundation of the mining industry. The selection of a loading and haulage system, then, is based upon safety considerations and an economic evaluation aimed at meeting the production requirements at a minimum cost per unit of production. Regular investigations into the excavation and hauling operations of a surface mine to ascertain the component cycles of excavation and hauling for both ore and waste is very necessary to update production and equipment scheduling plans. The individual costs of excavating and hauling of ore and waste are equally very relevant to the profitability of a surface mine operation. The results from the analysis shows that improving on the shovel-truck matching could further reduce the costs of excavation and hauling. The current falling of gold prices coupled with increasing ore hauling distance calls for low costs of operation in order to remain profitable. Thus the need to analyse these operations to improve on the efficiency and cut down their cost. This thesis report presents the results of a research work that was conducted into the excavation and hauling operations of Bogosu Gold Limited (BGL) to determine the individual costs of excavating and hauling ore and excavating and hauling waste. The excavating and hauling operations at BGL are described. The operations were assessed by observing the field operations in order to make informed suggestions. The results of time and motion studies conducted on the excavating and hauling operations of BGL were used to evaluate the costs of excavation and hauling.
