Abstract

While-drilling identification technology is a crucial part of intelligent mining development. The results provide a scientific basis for real-time adjustment of support parameters, promotes safe and efficient mining. Noise and vibration generated during the rock drilling process vary significantly between different rock materials, offering a new method for identifying rock characteristics. This study used a digital drilling test system to conduct experiments on layered rocks with weak interlayers, monitoring drilling parameters and borehole sound pressure and vibration acceleration in real time. Time-domain and frequency-domain features of borehole sound pressure and vibration signals were analyzed to identify rock characteristics in weak interlayer areas. The results show that these methods can clearly identify the location of weak interlayers. The spectral characteristics of different rock materials are significantly different, indicating a strong correlation between borehole sound and vibration characteristics and the mechanical properties of the rock. Comparing sound and vibration identification results with drilling parameters at weak interlayers verified the accuracy of the identification, providing a basis for lithology identification using multiple parameters. This study shows the importance of drilling noise and vibration parameters in enhancing while-drilling parameters in the digital drilling process.

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.
