Experimental studies of screw drill with frozen soil interaction
Introduction. The process of formation of wells in frozen soils is one of the complex processes of excavation. A drilling tool of a new geometric shape forms a well by brittle destruction of the rock. The purpose of the conducted experimental studies was to determine the effect on the energy intensi...
