English

Subject field(s)
  • Underground Mining
DEF

The rock above the immediate roof.

CONT

There are two broad types of roof as far as support is concerned, the immediate roof above the coal and the main roof. Artificial support for mining purposes is only concerned with the immediate roof as nothing except large blocks of solid coal, or massive concrete, will support the main roof. ... Main roof is composed of strata above the immediate coal bed roof that forms the overburden to the surface. Frequently, the term is applied only to a massive, strong rock layer that does not break or bend until all of the coal is removed by pillaring or by longwall mining.

OBS

Immediate roof: Lowest layer or layers of rock immediately above an underground opening.

PHR

Main roof break.

French

Domaine(s)
  • Exploitation minière souterraine
CONT

S’il s’agit d’une taille à foudroyage, le toit immédiat casse et s’effondre le long d’une ligne parallèle au front de taille à quelques mètres de celui-ci; les éboulis foisonnés remplissent le vide, de sorte que le toit supérieur, à quelques mètres au-dessus, repose sur ces éboulis, qui jouent le rôle d’un remblai, et les tasse progressivement [...]

PHR

Cassure d’affaissement, cassure d’exploitation (du, au) toit.

Record 2 1999-10-21

English

Subject field(s)
  • Extraction Procedures - Various (Mining)
  • Blasting Work (Mining)
DEF

A method of stoping in which the ore is extracted by excavating a series of horizontal (sometimes inclined) timbered slices alongside each other, beginning at the top of the ore body and working progressively downward; the slices are caved by blasting out the timbers, bringing the capping or overburden down upon the bottom of the slices which have been previously covered with a floor or mat of timber to separate the caved material from the solid ore beneath. ... As the slices are mined out and caved this mat follows the mining downward, filling the space occupied previously by the ore.

French

Domaine(s)
  • Procédés d'extraction divers (Exploit. minière)
  • Travail aux explosifs (Exploitation minière)
CONT

La méthode de la tranche horizontale unidescendante avec foudroyage est utilisée dans les couches de charbon fragile, épaisses et de forte pente. On exploite des tranches horizontales successives d’environ 3 m d’épaisseur dans l'ordre descendant, chaque tranche passant sous les éboulis de foudroyage de la tranche précédente. Avant de foudroyer par enlèvement du soutènement, on pose à la sole du chantier un plancher préalable, constitué de croûtes de bois posées sur des feuillards d’acier, pour former la couronne de la tranche suivante, l'isolant des éboulis frais, qui ne pèseront que modérément sur le soutènement [...] En variante, on peut exploiter en tranches inclinées.

Key term(s)
  • tranche unidescendante foudroyée
  • tranche horizontale unidescendante
  • tranches horizontales prises en descendant
  • tranches unidescendantes foudroyées

Subject field(s)
  • Underground Mining
  • Ore Extraction and Transport
CONT

top slicing: A method of stoping in which the ore is extracted by excavating a series of horizontal (sometimes inclined) timbered slices alongside each other, beginning at the top of the ore body and working progressively downward ...

CONT

cut-and-fill stoping: A stoping method in which the ore is excavated by successive flat or inclined slices, working upward from the level as in shrinkage stoping.

CONT

The section below is recovered in horizontal slices, by drilling flat holes and blasting against the space above.

Key term(s)
  • horizontal slices
  • flat slices

French

Domaine(s)
  • Exploitation minière souterraine
  • Extraction et transport du minerai
CONT

La méthode de la tranche horizontale unidescendante [en anglais :«top slicing»] avec foudroyage est utilisée dans les couches de charbon fragile, épaisses et de forte pente. On exploite des tranches horizontales successives d’environ 3 m d’épaisseur dans l'ordre descendant, chaque tranche passant sous les éboulis de foudroyage de la tranche précédente.

CONT

Les méthodes de tranches remblayées s’appliquent aux gisements dont la dimension selon la verticale est importante (filons, couches en dressants et parfois amas) : le minerai est abattu (et évacué) par tranches horizontales de 3 à 4 m de hauteur. Avant de passer à une tranche suivante, le vide créé est remblayé; la tranche suivante peut être au-dessus (tranches montantes remblayées, où le remblai sert de plancher de travail) ou au-dessous (tranches descendantes sous remblai).
