Predicting the production rate of diamond wire saws using multiple nonlinear regression analysis

In this paper, the prediction of production rate of diamond wire saws was performed. Performance measurements of diamond wire saws were conducted on 14 different carbonate rocks in mines located in Iran. Rock samples were collected from the mines for laboratory tests. Elasticity modulus, quartz content, and uniaxial compressive strength (UCS) were determined in the laboratory. Production values were correlated with the corresponding elasticity modulus, quartz content, and UCS. The sawing speed and rock properties were evaluated using multiple nonlinear regression analysis, and the developed model was validated by statistical tests and actual data of sawing speed for four new mines. It was concluded that the sawing speed of carbonate rocks using diamond wire saws can reliably be estimated using the developed model.
