Abstract
The article analyzes the impact of water inflow in a mine on the efficiency of the main mine water drainage system as a case-study of Udachny Mine, ALROSA. It is found that the content of solid particles in mine water grows with the increasing water inflow in the mine. A method is proposed to eliminate excessive water inflow in the mine in warm season in case of a pumping station teardown because of the spoil bank slide. The expected payback time of the proposed engineering solution is calculated.
