Abstract
Results of Geoelectric measurements within Obi
coal deposit show that the host rock which is shale
has resistivity ranging from 5 to 14 ohm-m and within
the shale exists a sub-section with resistivity from
15 to 30 ohm-m. Correlation with geological data
reveals that this section contains the thick coal
seams and is of the order of 60m thick generally,
Vertical electrical soundings (VES) have marked
out the anticlinal structure within the area, and
gave indications of three fault zones.
Self-potential measurements show one positive
and one negative anomalies. While the negative
anomaly is interpreted in terms of a fault zone the
positive anomaly is attributed to an elevation effect.
Gravity measurements show that positive gravity
anomalies exist over two fault zones in the area.
