Boxing is located in the lower reaches of the Yellow River, all of which are covered by loose rock layers. Quaternary loose rock pore water mainly exists in aqueous media such as medium sand, medium coarse sand and fine sand, forming multiple layers of loose rock pore water. Water-containing structure is interlayer confined water development. From the southeast to the northwest, the aquifer formation gradually becomes thinner with the Quaternary overburden, the thickness of the single-layer sand layer gradually becomes thinner, and the water richness gradually weakened. The chemical types of groundwater are mainly HCO 3 and HCO 3 ·Cl. The pore water of loose rocks in the middle and deep layers is decreasing from south to north, and the content of Cl - is increasing. From west to east, the percentage of HCO 3 - mg equivalent decreases gradually, and the percentage of Cl - mg equivalent increases gradually. The area enclosed by the groundwater level buried depth 40m is the controlled mining area.
