| Abstract | ||
| In many times, a good distribution and implementation of equipment and machines along the quarry faces is considered a challenge to the mining engineer or the quarry operator. Quarry equipment includes drilling machines, air compressors, loading equipment including loaders and/or excavators, in addition to the transportation fleet of high-tonnage trucks. These equipment cost large investments in the production processes and need high skill to be efficiently distributed and operated. In this investigation, study of the optimum distribution of the available drilling machines of different specifications and capacities along the faces of the lime stone quarry of Assiut Cement Company has been carried out. A mathematical model has been used to find several alternatives and to choose the best alternative. Calculation of the minimum number of drilling machines that satisfy the annual production plan is an important step to decrease production costs. | ||
