Application of Elastic Wave CT and Seismic Imaging in Goaf Detection

Abstract The author introduces the technical principles of elastic wave CT method and seismic imaging method, taking the detection results of a dangerous road in southern Shaanxi as a research example. The application effect of comprehensive geophysical methods in solving engineering exploration problems was analyzed and studied, and the two methods were mutually verified, improving the accuracy of interpretation. The results show that the elastic wave CT method and seismic imaging have high recognition and resolution ability in the detection of dangerous roads in goaf collapse areas, and are effective technical methods to solve such geophysical exploration problems.
