FIELD: mining.
SUBSTANCE: method of binding bottomhole zone of formation of unstable rock consists in creating filter by means of pumping composition into zone at amount of 0.5 of porous volume of bound rock containing % wt: carbamide resin 80.0, sal ammonia 1.0-3.0, sodium nitrite 1.0-3.0, water- the rest, in forcing hydrophobic liquid with one porous volume, in conditioning for reaction and hardening within 24 hours.
EFFECT: simplification of process of formation bottomhole zone binding with synthetic resins without significant reduction of their collecting properties.
