Acording to the ions content measured in water and calculated correlativity, it is shown that the source of water-full in the mine area is from surface water and Maokou limerock.

Marble karst development in Da-hong-shan mine caused a great deal of water bursting in mine shaft, sharply lowering ground water and large scale of surface subsidence.

Water filling sources of underground mine in Pingshuo mining area have Quaternary pore water, surface water, Permo-Carboniferous sandstone fissure water and Ordovician limestone karstic fissure water.
