Mechanical excavation is the most widely used method to remove both overburdenmaterial and ore at surface mining activities. In spite of the direct excavation of thesematerials by heavy duty machines is rarely possible, blasting before excavation iscommonly applied. The main purpose of blasting process is to disperse the planned amountof suitably fragmented material from the rock mass to haulage. Thus the huge rock masseswhich are not possible to dig and transport by duty machines are suited to diggable andtransportable conditions by blasting application. Therefore the most important aim ofbench blasting applications at surface mining is to provide suitable material for digging.There is no doubt that a good fragmentation provides the economy in size reduction(milling) during mineral beneficiation process as well as the possibility to optimize diggingand transporting costs.
