     choosing the optimized and proper haulage system in mines is the important factor and affecting the technical and economic respects. the pit limit becomes larger and deeper by continuation of the open pit operation. this increase of the pit limit causes that the transportation distance to be increased. therefore, revising and finding a new route for decreasing the distance and applying the substitution methods for the ore and waste haulage is necessary. both the economic force andincrease the energy value are the most important factors and verifying the application of in-pit crushing and conveying system to decrease the mining operations. the obtained results show the operations cost of the waste and ore transportation by trucks is about 3.5 times more than the in-pit crushing and conveying system costs in sarcheshmeh copper mine. in addition, the studies show that the truck system can be only used until the sixth year of the development planning of the sarcheshmeh copper mine. after that, by choosing the policy of increase of mine production, also increase of the transportation distance, the usage of the trucks system alone is not eligible. in this condition application both trucks and conveyers system together will be essential. in addition, the studies show that in sarcheshmeh copper mine by applying the trucks and conveyers together as inpit crushing, the number of required trucks and the operations cost will be reduced about forty two percentages and the confidence level of production continuity will be increased.
