Abstract In order to understand the occurrence position and thickness variation law of minable coal seam in Fangxing Coal Mine and determine the continuity of minable coal seam, the marker bed method was used for comparison, and the physical properties of rock and coal seam, the amplitude anomaly of curve, morphological anomaly and special morphological combination relationship, coal seam spacing and coal quality characteristics were supplemented for comprehensive comparison. The results showed that the characteristics of the marker layer in the area were obvious. The lithological characteristics of the relatively stable limestone and the bottom bauxite mudstone in the coal-bearing strata could establish four lithological marker layers to compare the coal seams. Although the occurrence position of the minable coal seams in the coal-bearing strata in the area changed, the overall characteristics of the coal seams were clear, the connectivity was good, the marker layer was stable, and the coal seam comparison was reliable.
