  • Underground Mining
DEF

The rock above the immediate roof.

CONT

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.

Au-delà d'une certaine limite, il y aura par contre fracturation des roches, puis éboulement (celui-ci s'amorçant aux points où la surcharge est la plus grande).

English

Subject field(s)
  • Heat Exchangers
CONT

Environmental samples from water distribution systems, including the inpatient's room, condensing tower, cooling tower and the roof, were taken for microbiologic analysis. Before the results were available, environmental consultants were hired to conduct immediate remediation/disinfection of the hospital water system and the cooling and condensing towers to reduce any possible sources of Legionella.... A new condensing tower, part of a three condensing tower system, was installed in the basement of the hospital powerhouse...

French

Domaine(s)
  • Échangeurs de chaleur
OBS

Aux fins d'analyses microbiologiques, des échantillons ont été prélevés dans le réseau de distribution d'eau, notamment dans la chambre d'une patiente, une colonne de condensation, une tour de refroidissement et sur la toiture. En attendant les résultats des analyses, on a retenu les services d'experts-conseils en environnement pour apporter des correctifs immédiats/procéder à la désinfection du réseau de distribution d'eau de l'hôpital, de la tour de refroidissement et de la colonne de condensation, et ainsi réduire les sources potentielles de Legionella.

Water jet assisted road headers, diamond insert pick trials, and thru-flush pick trials are attempts to reduce or control frictional ignition problems associated with drag-style bit cutting.

CONT

[Researchers] evaluated options available to deal with frictional ignition problems caused by sandstone channels and other incendive structures within the coal seam, immediate roof, and floor.
