The article reviews the basic principles of interaction between the cutting tools with the ground. Their advantages and disadvantages. It is carried out to determine the degree of relevance of the issues under research and to clarify the currently existing methods of solving them. We are especially interested in frozen soils, because the problem of the frozen soils’ development is one of the most serious to date. Most of the unexplored territories of the world lie under the snow cover in winter times. In the extreme north an acute problem of dealing with permafrost soils demands a rapid optimization of the cutting processes applied to frozen grounds. To this end, we developed a special milling and boring rig BME-2000 (Bore-Milling Equipment 2000), based on a machine excavator. It works on the principle of core drilling and is designed to develop permafrost and extremely durable surfaces such as asphalt and concrete. This article will try to formulate all the necessary questions for further research studies and to set objectives for further optimization of the cutting processes based on the BME-2000 as a comparison model. This will be done through a review of all known principles of excavation and existing machinery that deals with the development of soils/frozen soils and very durable surfaces.
