Three or more than three effective coalfield logging physical character parameters from the observational drill holes were used to analyze and compare anomalous characteristics of all curves for the purpose of detecting prominent features of coal seams and wall rocks and making qualitative interpretation of the bed of interest. The thickness-determining interpretation utilizes emphatically typical characteristic values of apparent resistivity and artificial radioactive curve anomalies to determine the depth, thickness and structure of the coal seam. The morphological feature, index horizon and correction method of the curve anomalies of various physical character parameters are sometimes also used to study individual coal seams.
