Application of Infrared Remote Sensing for Mine Exploration in Desert Zones and Mathematical Modelling

Abstract

In this paper, the applicability of a technology with using infrared sensing was elucidated for mine exploration in dry and desert zones 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 viewpoint of numerical simulation with an appropriate mathematical model, the exploration mechanism, the exploration limit, various factors which accompany the mine exploration were examined systematically. As a result, the following facts are found : (1) the infrared mine exploration with the aid of natural environment conditions, depending on surface emissivity and sunshine duration band, etc., has an optimum exploring condition, (2) the mine exploration becomes difficult with increasing the buried depth, (3) the exploration is difficult for the case where various contaminations or any vegetation exist on and in soil around mines.
