Five experiences in finding water from large wells in Qingshi Mountain area:
1, The groundwater level of thick limestone is generally deep, and when the water level is shallow, fractured zones and fault zones can be found.
2, Thick marl is generally not easy to drill a well, and a well with good water volume can be found when the supply conditions are good due to severe weathering and fragmentation.
3, The dolomitic gray layer is better in areas with longer seasonal spring periods and is generally not easy to drill wells.
4, When the supply conditions of limestone mixed with shale are very certain, the conditions are better.
5, In general, in the case of engineering drilling rigs, the water level in the limestone formation is not high enough to reach the area, which means that there is generally not enough water pump to continuously pump water.
