Method for fixation of large-fracture watered rocks at penetration of underground mine workings includes well drilling, implementation of hydrodynamical investigations in those, pumping in to drilled wells of injection solution. One determines geometrical parameters of inculation screen and angle of natural slant formed with free surface of injection solution in cracks and determines needed volume of injection solution from expression where V – volume of injection solution being pumped in, m3; – angle of natural slant, degree; – angle of inclination of cracks to vertical, degree; R – minimal needed value of propagation of injection solution in cracks, m; l – distance from center of working being fixed to ceiling of water-bearing horizon, m; L – length of section of underground working being fixed, m; mт – fracture cavity of rocks being fixed, mm; M – power of water-bearing horizon, m.
