Examining Rock Abrasiveness Using the Gouging Test
摘要
The degree of wear on cutters in mechanized excavation projects is significantly influenced by the abrasiveness of rocks. This paper investigates the Gouging abrasiveness test, a dynamic feature-integrated abrasiveness evaluation technique. The scratching tool can attack the rock’s surface in a dynamic mode, which is similar to the operational condition of a cutting tool in a field, using this method. The abrasiveness evaluations were conducted on a range of sedimentary and igneous rocks with the compressive strength ranging from 30 to 290 MPa. A correlation was observed between the abrasive index and two key rock properties, namely equivalent quartz content (EQC) and UCS. There is a positive linear correlation between abrasive index and the fundamental properties, according to the results. Furthermore, a prediction model was built using multiple linear regression. The correlation coefficient between the predicted and measured values is 0.702. According to an initial comparison with the Cerchar abrasiveness test, gouging is a useful method for assessing low-abrasive rock. To further assess the effectiveness of the proposed methodology, a thorough comparison is required.
