Abstract

Le procédé consiste en ce que le déplacement du point d'injection des agents gazéifiants est obtenu en obturant progressivement l'extrémité des tubages, soit par des injections pneumatiques de matériaux granulés inertes additionnés d'un matériau thermodurcissables, soit par la fermeture de soupapes disposées à intervalles réguliérs des tubages.
