The article describes the assessment of the predicted water flows at the site of the projected rock dumps, which was carried out using geofiltration modeling. When developing the model, we used actual data on capacities, filtration coefficients and water capacity, roof and sole marks of the selected aquifers, precipitation infiltration, as well as the projected dumps are located on the slope surface. We schematized hydrogeological filtration conditions in relation to existing natural conditions, taking into account the planned construction and operation of dumps, and also determined the maximum water inflow of underground and surface water into the drainage system. Based on the obtained data, the most effective version of the drainage system for the removal of underground and surface water from the territory of dumps has been developed, which will allow to perform the maximum possible interception of the flow of underground water and flood water, to form depression surfaces in the near-slope mass of the body of dumps, to prevent filtration deformations of the ledges and to ensure the normative bearing capacity of rocks. The provided drainage devices will ensure the overall stability of the ledges of the dumps, both during their long standing and during their constant formation.
