The explosive charge is designed for securing anchoring rods in the body of the rock mass. It consists of modified carbamide resin and a catalyst, contained in separate, easily destructible containers. Unique characteristics: The solution of phosphoric acid is the catalyst. The catalyst volume in the charge is equal to 1/4 of the volume of the carbamide resin, modified with sodium bicarbonate. The amount of the latter is adjusted to ensure air-frothing increasing the volume 2 to 3 times, and the gelation time of about 1 minute. |
