CALCULATION OF THE COEFFICIENT OF PERMEABILITY WITH THE USE OF HYDROCHEMICAL METHOD

The coefficient of permeability of the karst groundwater in Yanhequan basin of Shanxi Province was calculated using the chemothermodynamic and chemodynamic methods combined with the hydraulic and geological methods, The aquifers in Yanhequan basin were divided into five kinds according to their coefficients of permeability.It has been proved by drilling and pumping tests that the calculating methed is right.
