"An approach to optimal freezing of rock with the objective to increase the bearing capacity of the neighborhood of openings during tunneling is discussed in this study. Technique of internal parameters is used, which are calculated in zonal localities, subregions. Creating a priori influence matrices suitable algorithm can be achieved for optimal design of the solution for distributed temperature. Numerical procedure should involve results from experimental models prepared in stands, which are built up from physically equivalent materials. Comparison of results from experiments and numerical analysis (specific form of back analysis) enables one an achievement of very veritable results."@en .
