FIELD: mining.
SUBSTANCE: method for stabilisation of subsurface part, in which part of subsurface is put in contact with preflush fluid, part of subsurface is put in contact with strengthening fluid, containing resin and water decomposable dissolvent, and after-flushing fluid. Method for reduction of loose material formation from subsurface part, in which part of subsurface is put in contact with preflush fluid, strengthening fluid, containing resin and water decomposable dissolvent, and after-flushing fluid. Method for rupture of subsurface part with control of loose material formation, in which part of subsurface is put in contact with preflush fluid, strengthening fluid, containing resin and water decomposable dissolvent, with fluid for pressure rupture sufficient to develop or grip the fracture in subsurface part.
EFFECT: increased strength of fixation, no loss of permeability.
