Took 38 water samples from four of the main pouring water aquifers in the mining area in northern Anhui such as Linhuan Mine, Haizi Mine and so on, analyzed the content of the radioactive isotope tritium, and drew the content of tritium isoline figures about the fourth aquifer, the Taiyuan limestone aquifer and the Ordovician limestone aquifer.

Numerical simulation of the analysis of possibility of water inrush through fault;

Solid-liquid coupling study on water inrush through faults in coal mining above confined aquifer;

The enormous saline aquifers deeply buried in the sedimentary basins are saturated with high concentration dissolved solids,which make groundwater unsuitable to any large-scale exploitation.

Vulnerability assessment for unconfined aquifer in Guanzhong basin;

Calculation of typical unconfined aquifer seepage to a shallow lake with gentle slope bottom;

According to the framework of ModIME and experience in practice,problems existing in simulating unconfined aquifer are pointed out herein to avoid simulation deviation caused by the software itself.
