Abstract
Soutènement provisoire pour travaux de recoupage dans les galeries minières comportant des rallonges de poussee, qui sont disposées dans le sens longitudinal des galeries et portées par un cadre de soutènement, de façon que chacune de ces rallonges de poussée, dépassant le cadre de soutènement sur l'avant et sur l'arrière, soit coordonnée à un cylindre avanceur, caractérisé en ce que le cadre de soutènement 1 se compose d'au moins trois cintres 2, 3, 4 pouvant être déplacés, indépendamment l'un de l'autre, dans le sens longitudinal et/ou dans le sens transversal.Temporary support for recutting work in mining galleries comprising pushing extensions, which are arranged in the longitudinal direction of the galleries and carried by a support frame, so that each of these pushing extensions, exceeding the support frame on the 'front and rear, is coordinated with an advancing cylinder, characterized in that the supporting frame 1 consists of at least three hangers 2, 3, 4 which can be moved independently of one another, in the longitudinal direction and / or in the transverse direction.
