Title
(EN) METHOD FOR TAMPING EXPLOSIVE CHARGES INTO VEINS IN BEDROCKS
(FR) PROCEDE DE BOURRAGE DE CHARGES EXPLOSIVES DANS DES VEINES DE ROCHES DE FOND
Abstract
(EN)
The present invention relates to a method for tamping an explosive charge in a hole provided in a vein of a bedrock comprising the steps of inserting the explosive charge in the hole and tamping the hole with a sealant, whereby as a sealant, a foam forming polymer is inserted in the hole in the liquid state, the polymer is allowed to foam and harden.
(FR)
La présente invention concerne un procédé de bourrage d'une charge explosive dans un trou formé dans une veine d'une roche de fond comprenant les étapes consistant à insérer la charge explosive dans le trou et à bourrer le trou d'un agent d'étanchéité, de sorte qu'en tant qu'agent d'étanchéité, un polymère formant une mousse est inséré dans le trou à l'état liquide puis le polymère peut former une mousse et durcir.
