Abstract The axial part of the anticline in the deep mine is the stress concentration part. Under the action of external stress, the cracking of the axial part and wing part of the anticline parallel to or oblique to the fold axis first forms tension torsional fractures, which will form complex fault structures. When the coal mine develops and looks for coal near the anticline axis, the concealed fault structure has a great impact on the actual production. By analyzing the actual exposure of the fault structure near the anticline axis developed and comparing the original geological data, in the 1300 mining area of Xingdong Mine, Jizhong energy, the development law of the fault structure near the anticline axis was developed.
