METHODS FOR FIXATION, SUPPORT AND REPAIR OF MINE WORKINGS, MINE REINFORCED-CONCRETE TIGHTENING

摘要

Group of inventions relates to ore-mining branch and can be used in mining construction. Fixation of mine working is performed with frame fixation. Strength of frames exceeds strength of surrounding massif, this provides its cutting with frames at compression of massif. Inter-frame space is closed with reinforced-concrete tightening with armature. Armature has reserve able to increase its length at deformation. Support and repair of mine working is performed with separation of rock massif cut with frames and held with deformed tightening, with replacement of reinforced-concrete tightening to new. The inventions promote decrease of rock pressure on frame fixation and prolongation of its service life.
