ABSTRACT
The main equipment of the operating mines in Greece runned by PPC is electrically powered. The biggest mine uses diesel equipment consisting by shovels and trucks of big capacity varying from 50 to 136 T, for earthmoving of overburden containing hard formations, with annual rate of 15 MBCM. The Paper presents one method of cost estimation of earthmoving done by shovels and trucks. It is used in the example of feasibility study for a new mine using that equipment for earthmoving of 14 to 18 MBCM. The operation parameters used for the cost estimations are taken from real data selected from the operation of 136 T mining trucks in the mine mentioned, and from theoretical approach. The cost estimation method is helping to get fast the indicative BCM cost needed for the case of feasibility study or more generally speaking for new construction works.
