【 摘 要 】

In order to grasp the occurrence conditions of the Cretaceous aquifer in Longdong Ningzheng mining area, the types and laws of the aquifers in the area, hydrogeological characteristics, and recharge and excretion conditions were analyzed. The study found that the groundwater in the east of the Longdong Basin was replenished in three directions, and the south side was Excretion boundary. The early cretaceous aquifer is the most important groundwater in the Ningzheng mining area. The cretaceous aquifers of the Lower Cretaceous Huanhe Formation are widely distributed in the area. The shallow weathering fissures develop and communicate with each other, which is groundwater migration and a good place to live. The lithology of the pores and fissures of the Huanhe Formation is dark purple red siltstone and mudstone, which is a weak and water-rich aquifer. The lithology of the pores and fissures of the Luohe Formation is mainly purple-red and brown-red medium-grained sandstones. It is a medium-rich water-rich water-rich aquifer. The local borehole has a strong self-flowing water phenomenon. The aquifer recharge is mainly Subgrade recharge of the diving and infiltration replenishment of atmospheric precipitation.
