Feasibility study of the mining operation is one of the most important parts of the total mineral exploitation process. The economic importance of this, increases with the size of the mineral reserves. Gol-Gohar is one of the largest iron ore mines in Iran with an annual output of some 11 million tons. In this paper, the total costs associated with Gol-Gohar open cast mine have been calculated....

Vertical silos are large cylinders used for material storage in agriculture and mineral industries. One of the silo problems is its obstruction due to dome and dense packing. Depend on the material properties and silo dimensions several techniques are used to solve this problem. In the present work, possibility of obstruction solution of a laboratory silo by ball impact is investigated. Test ma...
