Abstract
Texture coefficient is one of the most effective physical factors in evaluating the engineering characteristics of rocks in various projects, such as drilling, cutting and advanced rate of full-face drilling machines. Evaluation of electricity consumption by disc-cutting machines is critical for monitoring and reducing expenses in the stone processing industry. In this study, the relationship between the textural characteristics of the rocks and the amount of electrical current consumed by the cutting machine in cutting hard stones was evaluated. For this purpose, ten samples of hard rock were investigated. For each rock sample, a microscopic slice was prepared. Then, five digital images were taken using the microscope from each division, and the values of textural characteristics, including area, perimeter, largest diameter, and most minor diameter of all grains in each embodiment, were determined. Then, the texture coefficient of all studied stone samples was computed based on the determined specifications. Finally, the relationship between the texture coefficient and the rate of electrical current consumed by the cutting machine was investigated using statistical models. The results revealed that although the electric current used by the cutting machine decreased when the texture coefficient increased in some samples, no significant relationship between the texture coefficient and the amount of electric current used by the cutting machine was observed for hard stone samples. It was also found that the impact of lubricant type on the cutting machine performance is negligible.
