Abstract
two methods of modeling of interaction between a mining machine working body and rocks are considered; a multi-cutter working body sum impact on rock stress-strain state in a cutter action zone is described; practicability of distributed forces application in math modeling is substantiated.
Highlights
Geokhods of a new generation are being designed [1]; a specific principle of geokhod operation requires a special working body (WB) [2, 3] There are many different types, configurations and design concepts of WB of tunnel boring machines (TBM)
To make the right choice and to determine rational parameters of mining machine WB it is necessary to evaluate the nature of interaction between the instrument and the rock face
Considering a complex nature of stresses in the rock face, it is practical to apply a method of numerical calculations, namely the Finite Element Method (FEM) for math modeling
