Abstract
Technique minière. Tuyauterie de remblayage pneumatique à déchargement frontal composée de tubes raccordés bout à bout, qui, au fur et à mesure de la progression du remblayage d'une zone sont désaccouplés à tour de rôle pour être déplacés de la largeur d'une portée de remblayage et assembles pour former une nouvelle ligne de tubes, décalée et prête à entamer une nouvelle phase du remblayage pneumatique. Les tronçons de tubes 6, suspendus au soutènement 1 ou posés sur le mur, sont reliés les uns aux autres par les éléments d'une transmission à parallélogramme déformable et chacun des tronçons 6 après avoir été désaccouplé par ouverture du dispositif de raccordement 9, peut être déplacé parallèlement à lui-même, selon une direction perpendiculaire, au moins approximativement, à son axe. Application: exploitation par tranches remblayées.
