Abstarct: In this research, eleven type of building rocks of Iran have been studied to predict of production rate of diamond wire saw. Determination of relationship between physical and mechanical properties with production rate is main reason in this research. In order to evaluation of the effects of texture on production rate in diamond wire saw, at first a thin section was prepared and then digital photographs were taken from each section. After this, all imaged were digitized using Auto CAD software. Then area, perimeter, longest diameter and shortest diameter were assigned. Other properties such as compressive strength, tensile strength, density, porosity, Los Angeles abrasion loss and Schmidt hammer value have been measured in laboratory and on the other hand cutting properties of the machines has been recorded in mines. The relationships between these parameters have been evaluated using simple and multiple regressions. To decrease the parameters in multiple regressions, the relation between the parameters has been studied. If there is good relation between two parameters, just one of them will be used in regression. In physical properties, area, and diameter equivalent and texture coefficient and in mechanical properties, compressive strength, tensile strength and Schmidt hammer value had good correlation coefficient. Final model will be with respect to these parameters.
