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. It is solved the optimizing of cost on coal quarries also. The situation on stone and coal quarries is different. There are requirements for stone production, but the production of coal is in decrement. Comparison and solving both situations seems to be useful. The relationships between different production proc...

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...
