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.
