FIELD: mining. SUBSTANCE: introduced into ground is ferromagnetic material treated by surfactants. Grout spreading beyond the definite zone is blocked by magnetic field acted on grout in rock mass. Grout is injected into rock mass through tube 3 on which magnetic field sources 7 are installed. Tube 3 serves as shield protecting from magnetic field effect. EFFECT: reduced consumption of grout and improved quality of consolidation of rocks due to blocking of grout spreading in preset directions in rock mass. 2 cl, 2 dwg
