Equipment and Methods for Studying Thermoacoustic Emission Memory Effects in Rocks

Abstract

Thermally stimulated rock failure has been actively studied for over 30 years for solving both fundamental and applied problems. At the same time, there are features that make it difficult to obtain information on the development of thermal compared to mechanical damage. The article discusses three main problems: the small number of recorded acoustic emission pulses, the difference in thermal conditions during heating and cooling, and the high level of interference from conventional heating control systems. The article analyzes ways to solve these problems and proposes and develops an improved laboratory setup and methods for studying thermally stimulated rock failure.
