Drilling is the traditional and still the most common method used in coal exploration. Most coal companies rely heavily on borehole data to evaluate their mine properties. However for the Underground Coal Gasification (UCG) and Coal Bed Methane (CBM) it is necessary to map the subsurface coal and to detect other spatial properties of the coal seam ...

Geophysical surveys, which use geoelectrical methods base on the variation of electrical parameters of the soil. To understand the phenomena in ground-rock medium, in which electric current flows, it must be realized that such substrate resists while electric current flows through it. According to Ohm's Law, resistance R is directly proportional ...
