Abstract

1. Dampening nozzle for barrier forming materials in underground mining and tunnelling, which is incorporated into the barrier forming material supply conduit and provided with a water connection, having a tube flange on both ends and having tangentially arranged, nozzle-shaped bores for the dampening water, characterized in that the tube (2) is formed to have an annular space (11) and that the bores (9, 10, 15, 16) opening into the inner tube (7) tangentially cut at right angles to the flow direction (13) connect the annular space with the flow space (12) and are arranged in several planes along the flow direction, in which the bores in each plane are arranged on the periphery of the inner tube displaced by 180 degrees from each other and that each plane is arranged rotationally displaced from the neighboring plane.
