CONSTRUCTION METHOD OF MOUNTING CHAMBER FOR MECHANISED SYSTEM Russian patent published in 2013 - IPC E21D23/00 

FIELD: mining.

SUBSTANCE: construction method of a mounting chamber for a mechanised system involves initial performance of a working-out of small width using a tunnelling machine, coal transportation using a conveyor as it is being performed; its further widening till design width and reinforcement of roof with short and long steel polymer anchors. When coal is being transported at performance of a working-out, a longwall conveyor is used and widening of the working-out is performed by means of a cutter-loader, by extracting coal strips from the working-out side to the full formation thickness throughout its length in the direction of the intended face advance, and reinforcement of roof above the first extracted coal strip is performed with long anchors installed in pairs, rows in mutually opposite directions; after that, extraction of strips and reinforcement of roof is performed in series with short anchors till the mounting chamber achieves design width.

EFFECT: increasing the speed of construction of the mounting chambers; improving stability of the mounting chamber.
