The profitability of dimension stone deposit exploitation in relation to the coefficient of utilization

Dimension stone is a highly valuable raw mineral material per unit of product. From the past experiences and literature it is known that for a certain quantity of commercial blocks, dimension stone a significantly larger volume of natural (raw) rock mass, should be dug (cut) out. Stone residue, resulting in gaining the commercial dimension stone blocks, is usually less value per unit of product. Profitability of the dimension stone exploitation in a deposit is directly dependent on the rock coefficient of utilization. It is therefore a priority task and a challenge to improve the efficiency of dimension stone deposits utilization and reduce the accumulation of mineral residue that would ultimately increase profits. Dependence of profitability on coefficient of utilization of dimension stone deposits can be best expressed by numerical models, as shown in this paper.
