ANALYSIS OF EARTH'S HEAT FLOW IN ARTIFICIAL GROUND FREEZING
The authors have analyzed relative earth heat infiltration in artificial ground freezing in the context of formation of frozen wall in mine shafts. The artificial ground freezing modeling reveals considerable dependence of the earth heat infiltration on the thermal properties of ground, process variables of freezing plant and time. The earth heat infiltration comes to a steady-state value 5-8 months after beginning of freezing. The formula is obtained for estimation of the steady-state value for the relative earth heat infiltration at different temperatures of ground and freezing brine.
