Numerical simulation of frozen wall formation in water-saturated rock mass by solving the Darcy-Stefan problem

Mikhail Semin, Lev Levin

Artificial ground freezing (AGF) is a common technology of shaft sinking through water-bearing strata. The AGF technique is used to create a frozen wall preventing shaft flooding. An additional factor that makes shaft sinking more…

Analysis of the structural integrity of a frozen wall during a mine shaft excavation using temperature monitoring data

Lev Levin, Mikhail Semin, Ivan Golovatyi

This paper describes the results of the temperature monitoring of a frozen wall (FW) around the skip shaft of a potash mine under construction. The data on temperature measurements in control-thermal boreholes were used to parameterize the…

THM-coupled numerical analysis of temperature and groundwater level in-situ measurements in artificial ground freezing

Anastasiia Kostina, Maxim Zhelnin, Oleg Plekhov, Kirill Agutin

Belarusian Potash salt deposits are bedded under aquifers and unstable soil stratums. Therefore, to develop the deposits a vertical mine shaft sinking is performed using the artificial ground freezing technology. Nowadays, real time…
