This work concerns thermal and mechanical processes in frozen rocks. Features of elastic and thermal properties of frozen rocks was researched. Anomalies of elastic and strength properties of alluvial rocks in a negative range of temperatures around 0 degrees Celsius are established. The numerical model for the description of rock’s pressure in underground mining opening was created. The method of finite elements is applied to creation of mathematical model and solution of Stefan’s problem in a surrounding massive of frozen rocks is solved. The software program text on a FORTRAN’s translator is applied.
