CONCLUSION In this study, a novel, web-based application was developed to automate lithological classification and rock quality designation (RQD) based on hyperspectral imaging and RGB imagery of borehole core samples. The application under discussion makes use of custom-built algorithms for hyperspectral segmentation and fracture detection. These were designed to support downstream assessments such as Rock Mass Rating (RMR) evaluation. The lithological segmentation module, trained using convolutional neural networks (CNNs), demonstrated high concordance with expert classification and maintained robust performance even when applied to hyperspectral data from sites not included in the training set. This underscores its generalizability and practical applicability across a range of geological settings. For RQD measurement, the application achieved an average absolute difference of 11.8 compared to manual measurements across multiple core images. When converted into RMR scoring, this corresponded to an average deviation of approximately 3 points. Notwithstanding this discrepancy, the system demonstrated a reduction in measurement time of more than 50%, thus substantiating its practical utility in scenarios necessitating expeditious field assessments. The integration of sophisticated algorithms within a userfriendly interface has been demonstrated to engender a substantial reduction in operational workload and cognitive demands, thereby expanding the application's usability to encompass non-specialist users. The system is a scientifically grounded and field-ready tool that has the capacity to enhance the accuracy and efficiency of geological evaluations in a range of applied contexts, including mining, tunnelling, and civil engineering.
