Abstract

Abstract

By screening the natural radioactive logging data to obtain the continuous radioactivity data of strata, according to the position relation between anomaly layer and coal seam, the paper recognizes 4 types of anomalies, including coal seam, inter-coal seam, above-coal seam roof and below-coal seam floor, and establishes a comprehensive evaluation method for radioactivity in primary geological environment of coalfields. Through the analysis of evaluation method and result, it is believed that the geoenvironment of Bayanshan coalfield, Huhenuoer coalfield, Fuxin coalfield and Pingzhuang coalfield in Northeast China are obviously radioactive, thus the exploitation should attach importance to the environmental impact of radionuclide migration.
