Drilling is a crucial operation in mining and construction, and optimizing it can significantly impact costs and operation time. Therefore, it is necessary to determine the parameters affecting the drilling and the correct understanding of these relationships can help to optimize the drilling operation. In the meantime, the relationships between the parameters of the drilling machine and the rock can be considered as a decisive operational condition. One of the effective parameters in drilling is the rock texture, which is measured based on the image analysis of thin sections. Additionally, the vibration caused by drilling can assist in determining the type of rock and its characteristics, guiding further operations. In this study, we utilized a laboratory-scale drilling machine to measure the vibration it caused during drilling and examined its relationship with the microfabric parameters of 10 different rocks. Statistical analysis indicated the highest and lowest correlation coefficient between vibration with aspect ratio and the equivalent diameter, respectively. These relationships can provide a good view of the impact of rock texture parameters on the vibration of the drilling rig on a laboratory scale. Also, by using the 3D surface plot and considering the combination of rock microfabric parameters, the drilling vibration can be predicted with much higher accuracy. This result shows that the drilling vibration is affected by a combination of rock microfabric parameters. [ABSTRACT FROM AUTHOR] |
