In-mine Geoelectric Methods for Detection of Tectonic Disturbances of Coal Seams

In-mine geoelectric methods - the geoelectric seam-sounding and geoelectric transillumination - were<br>applied for detection of fault zones in a coal mine. The measured data were interpreted using geoelectric<br>tomography algorithm. Appreciable agreements were found between the location of tectonic zones<br>predicted by the interpretation and those observed during the mining extraction.
