METHOD FOR ELECTROCHEMICAL ROCK CONSOLIDATION Russian patent published in 2007 - IPC E02D3/11 

FIELD: mining, particularly to construct underground mines and open pits in watered non-stable quaternary deposit rock having low permeability and to consolidate instable ground at building, building structure, motor road and rail road bases.

SUBSTANCE: method involves performing survey; determining electrical properties and strength of rock saturated with consolidation mix of used composition during mix hardening; establishing correlation between above properties; installing electrical sensors in zone to be treated between injection electrodes; measuring specific electric rock massif resistance and determining massif condition corresponding to demanded strength level; establishing correlation between specific electric ground resistance saturated with consolidation mix having used composition and different concentration before hardening stage initiation with ground strength after above mix hardening during normative hardening development period; measuring specific electric rock massif resistance during massif saturation with consolidation mix; stopping electric massif treatment when predictable massif strength is reached, wherein massif strength is predicted from determined strength dependence.

EFFECT: decreased material consumption, power and labor inputs to provide demanded consolidation quality in the case of non-uniform massif properties due to quick prediction of massif strength development at electric treatment stage.
