METHOD OF FIXING MINE WORKINGS WITH ANCHORS WITH REINFORCED BELTS Russian patent published in 2021 - IPC E21D11/15 

FIELD: mining industry.

SUBSTANCE: invention relates to the mining industry and can be used for fixing workings in weakly resistant rocks with any support that implies the connection of elements with each other. It is a method of fixing mine workings with anchors with reinforced belts, including sinking workings with the help of drilling and blasting operations, drilling holes, installing anchors and applying shotcrete-concrete to the surface of the workings. The fixing elements are hung to the anchors, which are metal corners with shelves, one of which has a hole in which the anchor is inserted, and the other has cutouts, in which reinforcement is threaded, thus forming the volumetric reinforcement structure, then a layer of shotcrete-concrete is put and a volumetric reinforced belt is formed.

EFFECT: use of the claimed method allows increasing the speed of work, resistance to dynamic loads and durability of the structure, as well as reducing support material consumption.
