Estimation of the performance of chain saw machines from shore hardness and the other mechanical properties

One of the most important factors affecting the production rates in quarry mining is the performance of chain saw and diamond wire saw cutting machines. In this study, Shore hardness, Schmidt hammer and uniaxial compressive strength values are used to predict the field performance of chain saw machines. Natural stone quarries are visited in Turkey in order to measure the field performance of chain saw machines. Different natural stone samples are obtained from different quarries for defining the physical and mechanical properties and Schmidt hammer and Shore scleroscope hardness values. The single parameter statistical relationships between Schmidt hammer hardness, Shore scleroscope hardness, mechanical properties and the field performance of chain saw machines are analyzed. Investigations indicate that there are strong relationships between field performance of chain saw machines and Schmidt hammer values, Shore hardness values, mechanical properties of natural stones.
