Shaft sinking in frozen soils with adoption
of blasting for rocks ripping in some cases leads destruction of freezing
columns. Such damages are coincided to rocks interface. At the same time, in
case rock stratification is absent in geological section, rapture of freezing
columns never has a place. Physical explanation of this phenomenon is possibly on
the base of wave processes, which having place in specific conditions of shaft
sinking with adoption of blasting works.
