Abstract
Laboratory tests of the physico-mechanical properties of enclosing rocks of the Botuobinskaya pipe are carried out at PJSC ALROSA in three wells 600 m in depth. The strength characteristics of rocks in thawed and frozen states are estimated. The research results of various lithotypes of rocks are presented and the dependences of their strength characteristics on moisture are found.
