Descrição: Rockburst is a nonlinear dynamic phenomenon that rock mass releases large amount of energy instantaneously along the unloading face of excavation.' Because of the characteristics of suddenness, destructiveness, unpredictability, rockburst has become a serious disaster for production and safety. The mechanism of rockburst is a difficult subject that has been widely investigated in the fields of mining, tunnelling and underground engineering. Appropriate monitoring methods are crucial importance to study the occurrence and mechanism of rockburst. In field monitoring of rockburst, many researchers use some necessary instrument for directly monitoring of engineering rock mass to distinguish whether there is a possibility of rockburst. Field monitoring methods mainly include seismic method, drilling cuttings method, microgravity method, etc. Infrared thermography, due to its non-destructive and non-contact testing nature, has been widely used in the field of rock mechanics.
