fis-2465	Semin, Mikhail; Levin, Lev	Numerical simulation of frozen wall formation in water-saturated rock mass by solving the Darcy-Stefan problem	2019	10	.pdf	application/pdf	4556	292	55	In [10], a thermo-hydraulic model of fluid-saturated rock mass was used to analyze how the heterogeneity of rock mass properties affects the formation of a frozen wall. The groundwater velocity is calculated from the Darcy’s law: r l l l k k p     v (4) where rk is the water relative permeability; k is the absolute permeability of rock mass, m2; l is the dynamic viscosity of groundwater, Pas; lp is the hydrostatic pressure in the pore space, Pa.	cache/fis-2465.pdf	txt/fis-2465.txt
