ARMOURING OF VERTICAL SHAFT Russian patent published in 2010 - IPC E21D7/00 

FIELD: mining.

SUBSTANCE: invention refers to mining industry, namely to structures of armouring of shafts and may be used in vertical shafts of coal and ore mines. Armouring of vertical shaft includes guides for lifting containers and dividers installed on anchor consoles which are fixed in shaft barring. Each divider is designed as two pipes arranged at selected angle with respect to each other in plane of armouring layer, which are rigidly connected between each other and are filled with hardening material in the form of concrete mix. At that guides are rigidly fixed near top of Y-connection of pipes from outboard side of divider.

EFFECT: improvement of maintainability of armouring of skip shaft and shaft with cage winding, reduction of metal consumption and decrease of aerodynamic resistance of airflow in shaft.
