Abstract Based on the actual geological measurement data of No.2 and No.3 coal seams in Hengtai Nanzhuang Mine, the geological structure characteristics of the minefield were analyzed and evaluated. After the evaluation, the geological types of the No.2 and No.3 coal seams were classified into medium type. The measurement data provided a reliable reference and basis for the mining of No.2 and No.3 coal seams and the prevention and control of underground disasters.
