ABSTRACT The paper presents results of the study which evaluated feasibility of introducing a trolley assisted haulage system to an Australian open pit mine. The study compared expected performance of the trolley system, an updated version of the systems used in several South African mines, to that of the fleet of mechanical drive trucks used by the mine at present leading to definition of site specific conditions under which the trolley system may become economically feasible.
