ABSTRACT
The article presents the results of the numerical experiments were designed to determine the effect of obstacles in the form of the drainage wells/piezometer on the basic efficiency parameters of the excavator’s work. Simulation research on built model included defining the basic parameters of the excavator working in the front block on stabile front (as a comparison) and on the non-stable front for two variants of drainage infrastructure exposing.
