The drainage system of the Grib deposit with implemented combined dehydrating is analyzed. Aimed to reduce water head in pitwall rock mass, as the depth of the open pit increases, horizontal drainage holes will be drilling from lower berms. Predictive designs of horizontal holes using numerical geo-flow modeling have no appropriate validation procedures. The authors have set and performed numerical experiments in VisualModflow environment in order to validate modeling procedure for horizontal drains. The key objective of the numerical experimentation is to determine conditions at hydrodynamic boundary of drains versus discreteness and geometry of numerical model, as well as parameters of a model horizontal hole. The numerical experimentation reference was chosen to be a horizontal drain hole with a length of 150 m and diameter of 0.2 m. By comparing heads and flow rates with the reference values, the hydrodynamic boundary conditions of drains were selected. The interaction of the above listed parameters is described, and the general recommendations are given for correct finite-element modeling of drain holes.
