Claims (3)

1. Способ упрочнения горных пород, включающий бурение по периметру выработки скважин, нагнетание в них воды, фиксацию участков с интенсивным выходом воды на поверхность выработки, нанесение изолирующего покрытия на отмеченные участки и нагнетание в скважину нестабильного цементного раствора способом с постоянным расходом, отличающийся тем, что по окончании первого нагнетания сразу после падения давления в скважине приступают ко второму нагнетанию раствора в данную скважину.1. A method of hardening rocks, including drilling along the perimeter of the wells, injecting water into them, fixing areas with an intensive exit of water to the surface of the production, applying an insulating coating to the marked areas and injecting an unstable cement slurry into the well with a constant flow rate, characterized in that at the end of the first injection, immediately after the pressure drop in the well, they start the second injection of the solution into this well. 2. Способ по п. 1, отличающийся тем, что при первом нагнетании величину расхода раствора в скважину устанавливают такой, чтобы седиментация цементных частиц в трещинах начиналась на удалении от их устьев, равном радиусу скважины, а при втором нагнетании, чтобы седиментация цементных частиц начиналась непосредственно от устьев трещин. 2. The method according to p. 1, characterized in that at the first injection, the flow rate of the solution into the well is set so that the sedimentation of cement particles in the fractures begins at a distance from their mouths equal to the radius of the well, and during the second injection, so that sedimentation of cement particles begins directly from the mouth of the cracks. 3. Способ по п. 1 или 2, отличающийся тем, что подачу раствора в скважину при первом и втором нагнетаниях прекращают в момент наступления излива раствора из трещин на поверхность выработки. 3. The method according to p. 1 or 2, characterized in that the flow of the solution into the well during the first and second injections is stopped at the time of the outflow of the solution from the cracks on the surface of the mine.
