Presented is a comprehensive review of the applications of acoustic emission in the field of rock mechanics. Acoustic emission experiments in rock mechanics were initiated in North America in the late 1930s as part of a study by the U. S. Bureau of Mines into problems associated with mine design and alleviation of rock bursts. More recently acoustic emission techniques had been employed to an increasing degree for the laboratory study of basic deformation and failure mechanisms in geologic materials. This paper outlines the major rock mechanics areas where acoustic emission techniques are being applied, and includes a brief description of a number of basic and applied studies.
