Abstract
Method for protection of mine workings against inflow of underground waters includes drilling of supercharge wells and dewatering wells and pumping in of plugging solutions to massif for arrangement of anti-filtration screen. Preliminarily one performs drilling of water lowering wells to bulk of covering rocks to decrease hydrostatic pressure of water there. Thickness of anti-filtration screen is set proportionally to head set as result of water lowering. Dewatering wells are drilled after arrangement of screen in insulated zone to all thickness of rocks being developed.
