METHOD FOR PREPARATION OF STOWING MIX Russian patent published in 2010 - IPC E21F15/00 

FIELD: mining.

SUBSTANCE: invention is related to mining industry, namely to method for preparation of stowing mix. Tails of dressing works are sent to several stowing complexes with application of hydraulic transport system, comprising working and drain branches. Tails are separated in each stowing complex into condensed product sent for preparation of stowing mix and lightened discharge. Working and drain branches of hydraulic transport system are separated. Tails from working branch are sent to each stowing complex, and lightened discharge is drained to drain branch. End part of working branch and beginning of drain branch in hydraulic transport system are joined by emergency bridge comprising stop valves. Each stowing complex newly added to system of hydraulic transport is duplicated with emergency bridge. System of hydraulic transport includes several separated working and drain branches, which service groups of stowing complexes that vary in number. Working and drain branches of hydraulic transport system for sending of tails to several groups of stowing complexes may be combined into headers.

EFFECT: provision of stable high quality of mines stowing, increased efficiency and safety of mining works, lower costs for preparation of stowing mix and transportation of dressing works tails in servicing of several mines.
