WebWithout a reliable design method for the leaching and seepage step of in situ leaching (ISL), problems such as low comprehensive resource recovery rate and frequent geological disasters such as landslides are prominent. This study established a simplified “liquid injection-collection” plane model of ISL with a linear barefoot type rare earth mine … WebAbsolute Permeability. The permeability of free space, μo, is. μo = 4π∗ 10−7 H/m μ o = 4 π ∗ 10 − 7 H / m. and is constant. The absolute permeability of another material can be expressed relative to the permeability of free space. Then, μ = μoμr μ = μ o μ r. Where is the dimensionless quantity called relative permeability.
