METHOD FOR CONSTRUCTION OF STOWING BARRICADE IN MINE WORKING Russian patent published in 2013 - IPC E21F17/107 

FIELD: mining.

SUBSTANCE: construction method of stowing barricade in mine working involves creation of rock bank from rock lumps in layers with passage of a drain pipe and installation of pneumatic bottles on the rock bank. In each layer, lumps of rock are loaded to covers made from metal mesh. Sizes of mesh cells are less than minimum size of rock lump and divisible ratio of mesh length to its width, which is equal to 2:1. Filled covers are laid in odd-numbered layers with a long side perpendicular to longitudinal axis of stowing working, and in even-numbered layers parallel to longitudinal axis of stowing working. Height of filled covers and their number as to the height of stowing working are determined depending on height of a pneumatic bottle in an empty state, height of stowing working, number of filled covers as to the height of stowing working, height of cover filled with rock lumps, and height of the pneumatic bottle in a filled state.

EFFECT: improving efficiency of stowing works.
