Evaluating the conditions of induced brines disposal in frozen rocks based on numerical experiment
While disposing wastes into permafrost soil we can expect two scenarios of the formation of brine lens: 1) its self-conservation for a long period of time or 2) its spreading over large areas and penetrating deep into frozen strata up to sub-permafrost water table. A numerical experiment was used to show that the main factor influencing the brine lens behavior is the filtration coefficient of initial (frozen) weakly permeable rocks. If the coefficient has the value of ? 0,0001 m/day we have the first scenario; if its value amounts to ?0,001 m/day we have the second scenario.
