  4. Abstract:
  5. The prediction of production rate in ornamental stones sawing is very important in cost estimation and process planning of the rock sawing plants. The main aim of this paper is finding a mathematical correlation between production rate and rock brittleness indexes. The utilized data have been collected from several stone factories in Iran. Seventeen different granite and carbonate rocks have been experienced sawing conditions with large-diameter circular saws. The laboratory tests such as uniaxial compressive strength and tensile strength, were carried out on the rock samples which were collected from these factories. The ratio of compressive strength to tensile strength (B1), the ratio of compressive strength minus tensile strength to compressive strength plus tensile strength (B2), and the area under the line of compressive strength and the line of tensile strength (B3) were used as brittleness indexes in this study. Then, the relationships between these brittleness indexes and production rate were investigated by using a regression analysis. The results show that, there is not a good relationship between the production rate and B1 and B2. However, the production rate correlates with B3 very well. Therefore, there is a reliable prediction for ornamental stones production based on B3 as a brittleness indexes
