Abstract: The article shows the special features of existing support-propulsion systems of tunneling machines, which necessitate the artificial increase in metal consumption, limit the areas of application and hamper the development of scientific and technical level of mining machines. A new class of tunneling machines – “geokhod” is presented in the work. The description is provided of the method of movement which excludes the force of gravity of the machine from the process ensuring the stability and the process of formation of traction and crowd forces. The article describes as well the principle of operation of outside the contour support-propulsion system of the geokhod. The variants of design solutions, their analysis and areas of application are pesented. The tasks are indicated which are to be solved with the creation of outside the contour support-propulsion systems, and the ways of development. The advantages and application prospects were reviewed.
