Abstract There are thermal infrared and acoustic emission signal changes in the rock fracture process. Therefore，it is of great significance to study the thermo-acoustic signal in the fracture process of fractured rock. In order to study the thermal-acoustic sensitivity of the failure process of different lithological fractures，uniaxial compression tests on samples of granite，basalt，red sandstone，limestone and marble were carried out，and the temperature of the free surface and the internal acoustic signal of the samples during loading process were monitored. A joint analysis index of thermal-acoustic sensitivity is proposed. The results indicate that the time series sensitivity of the combined thermal-acoustic index is as follows：red sandstone，limestone，marble，granite and basalt，but the peak sensitivity of the combined thermal-acoustic index is as follows：basalt，granite，marble，limestone and red sandstone. Thermal infrared temperature signal is earlier than acoustic emission signal. The joint index can avoid the lag of acoustic emission signal and the spatial limitation of thermal infrared. The thermo-acoustic signal and the stress have a good corresponding relationship in the fracture process of each lithological rock. The research can provide a useful reference for the analysis and prevention of sudden rock failure.
