Abstract: Based on the regional hydrogeological survey and the example of combined exploration well, and according to the theory of water storage structure, this paper analyzes the types and characteristics of water storage structure in the metamorphic rock area of Taihang Mountain, and points out that there are mainly weathering crust water storage structure, fracture water storage structure, layered water storage structure and dike water storage structure.The weathering crust and fracture water storage structure are prevalent and are the mainly direction of finding water in the area.According to the pumping test data of the combined exploration well, the correlation between the depth of the main effluent of groundwater and the water level of the standard borehole is analyzed, which shows that the standard water level decreasing by Power function when the depth of the effluent increasing.
