Baibiguan mine field is located at the junction of the east wing of Qilu arc fold belt and Fenhe River near the trough. The results of geological exploration on coal field show that the fold and fault structures in the area are mainly developed in the west of the area, with the strike mostly NNE and a few NW. The folds are mainly broad back and syncline, and the faults are mainly normal faults. The formation of the geological structure is the result of the comprehensive action of the structural stress field with different properties and directions.
