By means of geologic mapping,trenching engineering validation of drill,we found that the known boron deposit or boracic layer inosculate with the magnetic anormally extreme point,which slows that we can indirectly find boron deposit associated with magnetite by using high precision magnetic method for magnetite prospecting.

The author combinedtheory of three zones with practice,presented that the flooding foof aquifers include all aquifers above coal seam and below separation layer.

Isotope and geochemistry techniques are increasingly used in evaluating the hydraulic connecting between groundwater in different aquifers to improve the hydrogeology database.

Using the materials obtained from the pumping tests and the water level recentralizing tests,thecoefficients of permeability of the shallow loose aquifers of many places in Huainan Coal Mine area are calculated.
