FIELD: mining.
SUBSTANCE: method for strengthening of soft fractured modular solid ores involves drilling of wells of the first series and injection to them (at pressure of not more than 1.5 MPa) of microcement solution for filling of fracture cavity, drilling of wells of the second series between the first ones, and injection to them (at pressure of not more than 1.5 MPa) of solution of acryl resins or silica for filling of threshold space.
EFFECT: strengthening of soft fractured modular solid ores, increasing safety of works on construction of working-outs.
