Title
(EN) LUBRICATED BLAST HOLE LINER
(FR) REVÊTEMENT DE TROU DE MINE LUBRIFIÉ
Abstract
(EN)
A blast hole liner for use in deviated wells comprising a flexible tubing made from a woven polypropylene comprising material with the internal surface coated in lubricant configured to enable an increased feedrate of filling material into the tubing. In one aspect lubricant coats folded surfaces of one or more gussets configured to enable an increased feedrate of filling material into the tubing.
(FR)
Un revêtement de trou de mine destiné à être utilisé dans des puits déviés comprend un tube flexible contitué à partir d'un polypropylène tissé comprenant un matériau dont la surface interne est revêtue d'un lubrifiant conçu pour permettre une vitesse d'alimentation accrue du matériau de remplissage dans le tube. Dans un aspect, le lubrifiant recouvre des surfaces pliées d'un ou de plusieurs soufflets conçus pour permettre une vitesse d'alimentation accrue du matériau de remplissage dans le tube.
