Abstract
(EN)
Disclosed is a device for mining, comprising: a first tubular member defining a first passageway therein along a first axis; and a plurality of peripheral tubular members arranged coaxially around the first tubular member, the plurality of peripheral tubular members comprising a first set of peripheral tubular members and a second set of peripheral tubular members, wherein at least one of the first set of peripheral tubular members is arranged to allow a first fluid passing therethrough to flow toward a predetermined area outside of the device via a lateral side of the device, and wherein at least one of the second set of peripheral tubular members is arranged to allow a second fluid passing therethrough to flow toward the first passageway.
(FR)
L'invention concerne un dispositif d'exploitation minière, comprenant : un premier élément tubulaire définissant un premier passage à l'intérieur de celui-ci le long d'un premier axe ; et une pluralité d'éléments tubulaires périphériques disposés de manière coaxiale autour du premier élément tubulaire, la pluralité d'éléments tubulaires périphériques comprenant un premier ensemble d'éléments tubulaires périphériques et un second ensemble d'éléments tubulaires périphériques, au moins l'un du premier ensemble d'éléments tubulaires périphériques étant conçu pour permettre à un premier fluide passant à travers celui-ci de s'écouler vers une zone prédéterminée à l'extérieur du dispositif par l'intermédiaire d'un côté latéral du dispositif, et au moins l'un du second ensemble d'éléments tubulaires périphériques étant conçu pour permettre à un second fluide passant à travers celui-ci de s'écouler vers le premier passage.
