Based on three-dimensional seismic data volume, the structure, undulating shape, coal thickness and missing boundary of main coal seam were analyzed by means of time profile and attribute slice, which provided geological guarantee for efficient production of coal mine. In this paper, the coal seam floor in the exploration area was a NE-trending syncline fold as a whole, and there were many secondary anticlinal folds in its two wings. The dip angle of the coal seam changed greatly in the south wing of the main syncline, and the dip angle of the north wing was relatively gentle. It was found that there were 2 faults with throw less than 5 m, 4 faults with throw greater than 5 m and less than 10 m, and 3 faults with throw greater than 10 m. The variation law of coal seam thickness was very obvious, which was thicker in synclinal axis and thinner in anticline axis. The coal seam in the southern part of the exploration area was affected by the Mazhai uplift, of which the deposition was missing. On the whole, the coal measures strata structure in the exploration area was general, the coal seam deposition law was obvious, the occurrence was stable, and the mining geological characteristics were good, which was conducive to the production and development of enterprises.
