HE PROFITABILITY OF DIMENSION STONE DEPOSIT EXPLOITATION IN RELATION TO THE COEFFICIENT OF UTILIZATION

Abstract

Dimension stone is a highly valuable mineral raw material per unit of product. From the past experiences and literature it is known that for a certain quantity of commercial blocks, dimension stone should be dug (cut) out is significantly larger volume of natural (raw) rock mass. 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.
