Record 2 2015-04-15

English

Subject field(s)
  • Mining Dangers and Mine Safety
  • Mining of Organic Materials
DEF

A mine explosion caused by the ignition of fine coal dust. It is considered that an explosion involving coal dust alone is relatively rare. It demands the simultaneous formation of a flammable dust cloud and the means of ignition within it.

  • Exploitation minière (dangers et sécurité)
  • Exploitation de matières organiques (Mines)
DEF

Explosion se produisant dans une mine ou un dépôt de charbon lors de l'inflammation de poussières de charbon en suspension dans l'air.

Record 5 2003-04-28

English

Subject field(s)
  • Blasting Work (Mining)
DEF

In coal-mining, detonating tubes of explosives tamped a few feet into a coal seam.

CONT

The second fatal mine explosion... occurred... on October 3, 1906. Investigations concluded that it was caused by "shooting from the solid, "which provided both a large quantity of dust and a source of ignition.

CONT

The tragedy happened because of the miner shooting on the solid. ... From 1984 until recent years, mines continued to shoot down coal by shooting on the solid. Later mining laws forced the companies to do the shooting with a certified shot foreman using explosives furnished by the company.

OBS

to shoot from the solid: To get coal down from the face by substituting massive amounts of explosives for the tedious and time-consuming job of undercutting.

Record 9 1996-06-05

English

Subject field(s)
  • Air Pollution
  • Nuclear Waste Materials
CONT

Low-level radioactive wastes can exist in solid liquid or gaseous form. Any solid waste may give off a radioactive gas, as in the case of Radium 226 which gives off Radon 222 when it undergoes alpha decay. Water flowing through a solid waste may leach out soluble radioactive material(e. g., the acid leachates of some uranium mine tailings). As well, solid fine particulates of radioactive waste may take the form of a dust and be carried away on the wind, as in the case in the erosion of mine tailings. Equally, non-radioactive dust particles in the atmosphere can be contaminated with radon daughters as a result of electrostatic attraction. Furthermore, fine solid or liquid radioactive wastes can also take the form of aerosols that, once airborne, may be widely scattered.

Key term(s)
  • solid fine particulate

French

Domaine(s)
  • Pollution de l'air
  • Déchets nucléaires
OBS

Voir aussi «particule», «particules», «particules en suspension», «particules solides en suspension», «particules de poussière» et «aérosol».

Record 11 1996-03-18

English

Subject field(s)
  • Air Pollution
  • Nuclear Waste Materials
CONT

Dusts are formed by the pulverization of solid matter into small size particles. These may be the result of such processes as grinding, crushing, blasting and drilling. Particle sizes range from 1 [micron] up to about 100-200 [microns]. Dust particles are usually irregular in shape. Examples include flyash, rock dusts and flour. They are heterogeneous in size and structure.

CONT

Any solid waste may give off a radioactive gas, as in the case of Radium 226 which gives off Radon 222 when it undergoes alpha decay.... solid fine particulates of radioactive waste may take the form of a dust and be carried away on the wind, as in the case in the erosion of mine tailings.

CONT

Ces particules de poussières microscopiques représenteraient de toute façon une fraction importante des nuages observés, puisqu'environ 10 % de la masse totale pourrait être sous forme de grains de taille inférieure à 0.005 micron.

OBS

Le terme «poussière» possède aussi un autre sens, plus général que la notion étudiée ici, où il devient synonyme de «particule». Bien sûr, dans une expression comme «particule de poussière», il reprend son sens spécifique : particule de moins d'un micron.
