FIELD: mining.
SUBSTANCE: method for reinforcement of mines includes drilling of inclined wells at roof and bottomhole coupling aligned at each cut of vertical wells, with length exceeding length of cuts by value of anchor locking part, installation of anchors in them and engagement of vertical and inclined anchors with their end parts at each cut. Fixation of anchor ends is done with the help of support angle having holes provided in its shelves, and nuts, one of which is used to tighten vertical anchor, and the other one is used to tighten anticipatory inclined anchor. At the same time number of cuts along length of inclined anchors in front row is selected depending on condition of roof rocks in front of bottomhole.
EFFECT: improved stability of mines roofs in areas of highly cracked rocks and in zones of ruptured tectonic disturbances.
