FIELD: mining. ^ SUBSTANCE: at first there are defined boundaries of dangerous area of water course, from the side of which it is possible inrush of water in area of course, and position of bottom boundary of course talik, formed in the basis by water course at warm period of year. After what on dangerous section of water course, in the range of its course talik it is implemented pipe, providing receiving and passing at least underground water, moving by course talik at cold period of year. Additionally outside pipe is coated by heat insulator and it is covered by ground, and at upper area of dangerous section of water course pipe intersects antifiltration component, which is overlapped by course talik. ^ EFFECT: reliability improvement ensured by reduction of thermal action water course on frozen rock. ^ 3 cl, 4 dwg |
