Zusammenfassung:The invention relates to a coal mine area coal seam abnormal thickening master control geological action type analysis method, and belongs to the field of gas outburst, and the method comprises the following steps: S1, building a coal seam abnormal thickening master control geological action type classification table; s2, aiming at the abnormal thickening area of the target coal seam, detecting and analyzing a profile distribution pattern of the abnormal thickening area, whether a structure exists around the abnormal thickening area, a distribution characteristic and a lithology distribution characteristic of a coal seam floor where the abnormal thickening area is located, a distribution characteristic and a lithology combination granularity change characteristic of a coal seam roof where the abnormal thickening area is located, and a paleo-geographical environment characteristic of the coal seam where the abnormal thickening area is located at an initial deposition stage; construction and evolution character
