The possibility of Infrared Camera Thermography for assessing the real time stability of underground excavations
Abstract: Rockbursts under high stress environment and rockfalls in discontinuous rock mass are of prime concerns during underground excavations. One of the authors [1,2] and his group performed a series of tests on minerals and rocks ranging from soft to hard, which showed distinct heat releases before the rupture. This fact implies that infrared camera thermography should be of some value for assessing...
