“…We can gain the stress fields by comparing the relationship between temperature and stress. As one kind of effectual and economy supporting technology, bolt support has been applied in many engineering fields such as mining engineering, metallurgy engineering, hydroelectricity and tunnel [6][7][8][9]. However, there are not effective techniques and devices to directly monitor the construction quality and work condition of bolt now.…”

The Infrared radiation experiments on bolt and rock in the process of loading were carried out. The results show that the infrared radiation temperatures rise wholly and uniformly before stress peak with increase of loading. The bolted rock presents local dissimilation in the thermal image after stress peak. The multi-layer round infrared radiation isothermal lines is formed around bolt. The temperature gradually reduces from inside to outside.There are 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 reflect the spatial and temporal features of infrared omens respectively. Keywords-infrared image;infrared omen;bolt;rockI.
