Abstract
Method for insulation of vertical mine workings against inflow of underground waters includes drilling of supercharge directed in radial directions horizontal wells to walls of working and pumping in plugging solution to wells. One performs drillilng of additional directed in radial directions inclined wells. At that first one forms screening horizontal screen through pumping in plugging solution to horizontal wells and then one carries out plugging of water bearing horizon through directed in radial directions inclined wells.
