[0002] Core logging is a crucial step in obtaining firsthand field data, and the accuracy of core identification plays a decisive role in the quality of exploration work. Traditional core identification methods mainly rely on the visual observation and experience of geologists, using basic tools such as tape measures, compasses, protractors, and ordinary calculators to measure and calculate parameters such as core recovery rate, yield rate, RQD (Recovery Quality Index), and fracture dip angle. Especially for the identification of gravelly soil layers, the percentage of gravel mass relies heavily on the subjective judgment of geologists, which, due to differences in experience, can easily lead to data deviation and distortion. Traditional core identification methods are cumbersome and time-consuming, requiring a variety of tools, and their reliance on personal experience makes it difficult to meet the requirements of geological exploration for data accuracy and objectivity.
