Sažetak
The coefficient of utilization of rock directly affects the profitability of the dimension stone deposit exploitation. Dimension stone is a highly valuable raw mineral material per unit of product. Past experience and literature show that for a certain amount of commercial dimension stone blocks, a significantly larger volume of raw rock mass should be dug up. Mineral residue as a result of the extraction of the commercial dimension stone blocks is usually the material of less or even minor value per product unit. Profitability of the exploitation of dimension stone in a reservoir 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 deposit and to reduce the accumulation of mineral residue that would ultimately increase profits. Numerical models can clearly demonstrate the influence of the coefficient of utilization on the exploitation profitability of the dimension stone deposit, which is presented in this paper. From the analysis of the real "in situ" performance and numerical models, the coefficient of utilization can be determined whereby the exploitation of dimension stone deposit is on the edge of profitability.
