ABSTRACT

The annual extraction of aggregates in the Czech Republic is between 45 - 50 mega tones. [5]. Many studies for better results of quarries are undertaken. In this paper is solved the question of optimizing.
The relationships between different production processes in quarries are very important matter. On the relationships between the manufacturing processes depends the economic effect of operation. The paper presents patterns in the organization of mining, which mutually related. Using computational methods and the program provides the optimal arrangement of production cycles to achieve the maximum possible profit of stone quarry.

Keywords: Quarry, fragmentation, drilling, blasting, cost of production, cycles, total cost of the quarry, revenue profit.
