METHOD FOR FIXATION OF ACUTE-ANGLED COUPLINGS OF MINE TUNNELS |
摘要 |
FIELD: mining. ^ SUBSTANCE: invention is related to mining and construction of underground structures, namely to method for fixation of acute-angled couplings of mine tunnels. Method for fixation of acute-angled coupling of horizontal and inclined mine tunnels with anchors includes the following stages: their fixation along perimetre with mine-run anchors in process of tunneling, installation of through horizontal anchors from root into adjacent mine with lag from the bottomhole of the latter, installation of deep anchors into wedge-like block between mines in zone of their considerable mutual effect from root mine in direction of adjacent one before start of adjacent mine tunneling. ^ EFFECT: preliminary strengthening of acute-angled block between branching mine tunnels, reduced hazard of shaft-sinking and tunneling works. ^ 2 cl; 3 dwg |
