ABSTRACT: According to the hydrogeological conditions, dynamic characteristics of tectonic deformation and geometric features, the fault structures inthePanxie mining area were divided into seven types respectively were horst, graben,graben-horst combination, forward (reverse) thrust structure, imbricate thrust structure, strike-slip structure,and others.Meanwhile,theq-structural styles boxplot had been constructedto analyze the water abundance of the karst formation aquifer.Ithasbeenverifiedvia the practical drilling core data. The final resultswere that the water-rich characteristics of the deep karst water controlled by the seven structural styles were different. The water abundance of graben-horst combination structure was strongest; the next was the horstin deep whichwasstronger than the graben. Then, the imbricate thrust structure, strike-slip fault,and other structural styleshad low water abundance in deep karst aquifer. The results can be aimed at differentstructural styles to guide the prevention and control of karst water hazardson the floor of Group A coal mining.
