ERECTION METHOD OF LINER OF INCLINED OR HORIZONTAL SHAFT, AND SECTIONAL STEEL FORMWORK FOR METHOD'S IMPLEMENTATION Russian patent published in 2014 - IPC E21D11/10 

FIELD: mining.

SUBSTANCE: erection method of a liner of inclined or horizontal shafts provides for construction in the inclined or horizontal shaft of the mine working of a supporting frame with scaffolding for performance of work, which forms at least two parts corresponding to the arch surface. The following is performed during work execution: anchors are installed, which fix the frame in the mine working shaft; a set of screw turnbuckles determining the design position of the arch is fixed on the scaffolding and in upper part of the arch bottom; a set of jacks determining the design position of the arch is fixed on the scaffolding and in the lower part of the arch bottom. A sheet bottom of the arch is fixed on the supporting frame; a shield bottom of a tray is suspended on movable beams of the supporting frame; laying of concrete mixture, dismantling of the formwork and movement of the supporting frame in inclined or horizontal shaft of the mine working is performed.

EFFECT: improving erection quality of horizontal mine workings owing to improving location accuracy of a formwork and due to quality of concrete application onto the shaft surface.
