Abstract The infrared radiation experiments on bolt and rock in the process of loading were carried out. It was found that the infrared radiation temperatures rose wholly and uniformly before stress peak with increase in loading. The bolted rock presented local dissimilation in the thermal image after stress peak. The multi-layer round infrared radiation isothermal lines were formed around bolt. The temperature was gradually reduced from inside to outside. There were two kinds of infrared omens for bolted rock fracturing, i.e., the infrared thermal image anomaly and curve of infrared radiation temperature and time anomaly, which reflected the spatial and temporal features of infrared omens respectively. The curve of infrared radiation temperature and time anomaly was temperature drop. The infrared thermal image omen was classified as high-temperature strip and low-temperature strip.
