Calculation of Permeability Coefficient Based on Underground Dewatering Test
LIU Ji
Abstract：In order to explore the hydro-geological conditions of the sandstone aquifer in 2-2 coal seam roof in Muduchaideng Mine, the permeability coefficient was obtained by underground dewatering tests. Based on the dewatering test data of the temporary bin, the steady flow and unsteady flow were respectively used to calculate the permeability coefficients, and through the contrast analysis, the permeability coefficient was finally determined, which thus provided the basic data for the calculation of mine water inflow.
