Abstract

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.

期刊介绍： Engineering geology is defined in the statutes of the IAEG as the science devoted to the investigation, study and solution of engineering and environmental problems which may arise as the result of the interaction between geology and the works or activities of man, as well as of the prediction of and development of measures for the prevention or remediation of geological hazards. Engineering geology embraces: • the applications/implications of the geomorphology, structural geology, and hydrogeological conditions of geological formations; • the characterisation of the mineralogical, physico-geomechanical, chemical and hydraulic properties of all earth materials involved in construction, resource recovery and environmental change; • the assessment of the mechanical and hydrological behaviour of soil and rock masses; • the prediction of changes to the above properties with time; • the determination of the parameters to be considered in the stability analysis of engineering works and earth masses.
