Abstract

The permeability coefficient decides the land water retention ability to some extent. This study measured soil permeability coefficient in land of coal mining areas with double ring method, in order to show the soil water retention ability and analyzed the relationship between soil infiltration curve and land water retention ability. The results show that soil infiltration curve is affected by the soil texture and soil moisture. If the soil moisture is adequate, the initial permeability curve of soil is steep, oppositely, if the soil moisture content is deficit, the initial permeability curve of soil is flat; for the different soil texture, the stable infiltration rate is largely different, meanwhile, permeability coefficient of sand is larger than that of silt, and the silt is greater than the clay.
