抄録

A corresponding distribution of electric potential is produced in a porous medium like sand and an aggregation of broken rocks, if a temperature distribution exists in the medium. The authors performed model experiments to investigate whether the measurement of the electric potential distribution can be used for locating the heat source. The main parameters measured are electric potential and temperature. The results of the experiments show that a distribution of electric potential is always created corresponding to the conditions of the heat source. It is concluded that there is a possibility that the measurement of potential distribution can be used for locating the heat source of spontaneous combustion of coal.
