Both seismic attribute technique and seismic facies analysis were used in the interpretation of coal erosion zones. Firstly, attributes were extracted from the reflection of the coal seam. Secondly, these attributes and the response characteristics of erosion zones were comparatively studied. Finally, the erosion zones were explained synthetically with attributes of sensitive response, and the erosion was determined. A comparison with the traditional method of drilling shows that the seismic attribute method can locate the coal erosion boundary accurately.
