Numerical Simulation Study on Detection of Subsurface Microcrack Using Active Infrared Thermography
Bursting of brittle rock is an abrupt and violent phenomena of rock failure in high stress mines that result in many irreparable losses, including human lives. In general, large number of microcracks initiation and propagation in rocks lead to the spalling of rocks in underground construction, therefore detection of microcracks and location of its amalgamation help to adjudge the stability and to give the early warning indications. A simulation study has been carried out using FEM software to examine the potential of subsurface microcracks detection using pulse infrared (IR) thermography. Using this proposed method, the potential collapse location along with crack depth and size of rock can be estimated. A box-shaped granite rock with artificially planted microcracks of different width and depth has been geometrically modelled. A 3D convective heat transfer equation along with coded pulse input has been used to check the detection potential. A phase mechanism was adopted for extracting the features based on fast Fourier transform technique using MATLAB code. Further, single-pixel temperature profiles at the surface of sound zone and cracked zone of the test samples were compared. The proposed predictive analysis may help to reduce the casualty that is caused by rock burst.
