Due to Tao’er Mine expanding area influenced by coal measures strata concealed thick layer magmatic rock, coal seam went bad for anthracite, part went for natural coke, based on the apparent resistivity logging curve of physical parameters in this area, physical characteristics of scattering gamma, natural gamma analysis, comparison, the clear distinctions between physical characteristics were found out, combined with parameters curve, which directly used the curve interpretation, logging parameters and effectively differentiated anthracite coal and natural coke.
