Record 1 2006-08-10

English

Subject field(s)
  • Mine Passages
DEF

The main working gallery or entry of a coal seam which dips at an angle and along which mine cars are hauled ...

CONT

Three methods, drift, slope, and shaft(or various combinations thereof), are used to gain access to coal located too deep underground for surface mining.... A slope is an inclined opening driven to work a seam with a downward inclination, or to reach from the surface to a seam or between seams.

OBS

When not open at one end to the surface, it is known as an inside slope.

French

Domaine(s)
  • Galeries et soles (Mines)
DEF

[...] galerie [en pente] débouchant au jour.

CONT

Lorsque le gîte est à profondeur modérée, on l'atteint à partir de la surface par une galerie inclinée, ou «fendue», dont la pente admissible est limitée à environ 18° [...]

OBS

Lorsque la pente est forte, c'est un puits incliné.

Record 2 2001-04-01

English

Subject field(s)
  • Spacecraft
  • Astronautics
CONT

Out-of-plane corrections are used to correct the steady drift of inclination caused by the solar wind. Inclination drift degrades the ground-track maintenance at high latitudes.

  • Engins spatiaux
  • Astronautique

Record 3 1999-05-11

English

Subject field(s)
  • Underground Mining
CONT

The rock mass is first fractured by drilling and blasting and then mucked out through drift headings underneath the rock mass cave. It qualifies as a safe mining method because the miners always work inside drift-size openings.

OBS

heading: A roadway driven in a coal seam, unless it is a hard heading which is driven in stone. A coal heading does not normally follow the strike of the seam - it is usually driven to the rise or to the dip. In Longwall stall mining, the stalls are turned off the headings.

OBS

drift : A passageway driven in the coal from the surface, following the inclination of the bed.

French

Domaine(s)
  • Exploitation minière souterraine
OBS

Sous le terme générique anglais de «drift» qui s'applique exclusivement à des galeries creusées dans la direction du gisement (en français «traçage»), on regroupe toute la variété des galeries : voie de fond, voie de niveau, galerie en direction, galerie de roulage, etc. Pour simplifier les choses, nous n'établirons qu'une seule différence générale entre galerie (drift) et travers-banc (cross-cut). Le travers-banc (cross-cut) désigne une coupe en travers du gisement; son rôle, en recoupant la veine, est essentiellement d'établir la connexion entre les voies de roulage de niveau creusées dans le gisement. Le travers-banc sert également dans les travaux de recherches ou de prospection. La galerie (drift), creusée dans le gisement d'après son vrai sens de galerie en direction ou de niveau, a une triple fonction : a) elle sert de base à l'exploitation des chantiers (stopes); b) elle est utilisée comme voie de roulage [...]; c) elle sert aussi subsidiairement comme voie de recherches dans les travaux de prospection.
