Abstract
Among the reliable tunneling complexes, without which it is impossible to create conditions for such a high-performance process, as mining of mine workings are geokhods. Since the geometric parameters of the external engine and the screw channel vary, the process of interaction of the geokhod systems with the geo- environment and with each other requires mathematical modeling. Modeling allows presenting schemes of interaction with various environments: loose (viscous-mobile) and strong. The mobility of the geoenvironment provides interaction along the entire supporting surface of the blade, so increasing the blade area leads to an increase in tractive effort. In strong rocks, the interaction occurs along the supporting surface of the blade, and the free surface may not touch the rock. Thus, in the interaction of the external propeller (HP) with the geoenvironment, the blade deforms; it is possible to form a region of crushing of the rock, and taking into account the elastic deformation in determining the geometric parameters of the blade and the canal will minimize the process of forming the region of crushing; when modeling the process of interaction of the VD with the medium, the load can be considered as uniformly distributed and equal to the ultimate strength of the rock for uniaxial compression.
