Fundamental Research of Wave Phenomenon in Frozen Rock Massif during Shaft Sinking

摘要

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.
