摘要：
FIELD: mining.SUBSTANCE: invention relates to the mining industry and can be used for quality control of the workings of pipe-work with friction-type tubular anchors. Method is proposed for determining the bearing capacity of a tubular anchor, which is realized as a result of a sequence of actions: inserting into tubular anchor 1 of spacers 3, the axial movement of traction element 4 is performed by screwing nut 6 on thread 7 to fix spacers 3 on inner surface 8 of the tubular anchor, installing support frame 9, installing loading device 12, axial loading of pulling member 4 through loading device 12.EFFECT: ensuring the force loading of the tubular anchor installed in the hole.8 cl, 10 dwg
