METHOD OF HYDROMINING OPERATIONS Russian patent published in 2008 - IPC E21C45/00 E21F15/00 E21C41/18 

FIELD: mining.

SUBSTANCE: invention is referred to a mining industry and can be used in development of firm minerals. The method of hydro mining operations includes hydraulic crushing of a rock bed, hydro transportation of broken off rock, supply of stowing material in a worked out room using a pipe line. Loose rock is enriched and dehydrated, and the waste received at beneficiating of loose rock is blended with a pulp received at dehydration of loose rock. The obtained mixture is used for filling the waste area. Sacciform resilient perforated shell is put in the waste area. Further on, it is connected with the filling material pipe and filled with filling material under heavy pressure. The flowing fluid obtained by perforation is collected and sent for treatment and recirculation.

EFFECT: better filling reliability of the waste area and safety of mining operations, lower expenses for filling, improved ecological situation on mine and in its neighborhoods due to fluid recirculation in the technological process.
