| | Abstract | | In this paper, the applicability of a technology with using infrared sensing was elucidated for mine exploration, where it is comparatively easy to specify the surface emissivity. It is very important to avoid the danger pertaining to mine exploration as much as possible by using an appropriate nondestructive testing method. From the viewpoints of empirical investigation and numerical simulation with an appropriate mathematical model, the exploration mechanism, the exploration limit, various factors which accompany the mine exploration are examined systematically. As a result, the following facts are found. It is clarified that the numerical simulation considered the effect of water content ratio on thermo-physical quantities have a great improvement in reproducibility of the experimental value, compared with the numerical simulation without considering water content ratio. We say that the water content have a great influence in infrared mine exploration except for the influence factors which was informed in previous report. |
