METHOD FOR ROCK HARDENING BY MEANS OF CEMENTATION Russian patent published in 1995 - IPC

FIELD: mining. SUBSTANCE: method involves drilling wells to set gages in one of them, pumping in hardening mortar and carrying out interval-by-interval the mortar penetration control taking into consideration change in parameter value with time during the pumping-in process. The pumping-in mode is corrected according to the control results. Electric filtration field intensity determined in the planes running in perpendicular to the well axis is used as parameter. Corrections on pumping mode are performed at the moments the filtration field intensity is fallen to zero within the hardening zone. EFFECT: enhanced effectiveness of the method. 2 dwg
