Evaluating the Stability of Geologic Structures Using Acoustic Emission

Source

This paper describes the application of acoustic emission to the study of geologic structures. Evaluation of the overall mechanical stability of large-scale geologic structures such as underground and open-pit mines, highway and waterway cuts, petroleum reservoirs, and underground gas storage reservoirs is extremely complex. Acoustic emission appears to be one of the most suitable techniques available for such purposes.

A brief review of the associated literature is presented along with a description of a mobile monitoring facility developed by the writer for field use. Two current field projects, associated with underground gas storage and longwall coal mining, presently underway by the writer are described.
