English

Subject field(s)
  • Mining Dangers and Mine Safety
  • Underground Mining
DEF

The sudden failure of walls or pillars in a mine caused by the weight or pressure of the surrounding rocks, and accompanied by a violent release of energy.

CONT

Rock bursts. In areas of very deep mining, as additional weight is supported by the pillars on the coal face, stresses may so build up that the yield point is reached. If the coal pillars, the roof, or the floor are able to yield gradually, the effects of the stresses are relieved by floor heaving, or by pillar or roof failure. Where the coal or the associated rocks are particularly strong and depths are much above average, these stresses may be relieved by rock bursts, which are relatively violent outbursts of the coal into the rooms and entries. Frequently, a large volume of gas (usually methane) is suddenly released during a rock burst in a coal mine.

OBS

for "coal burst" : Rock bursts and "coal bursts" in coal mines are generally designated by the term "bumps" or "bounces". A large proportion of these "bumps" or "bounces" are actually "coal bursts" due to fracturing of pillars and remnants and need not involve any fracturing of roof or floor rock.

OBS

for "air blast" : In former years rock bursts were sometimes referred to as "air blasts". This name originated from the fact that large quantities of rock loosened by some of the larger rock bursts displaced quantities of air, with the result that a blast of air passed through the mine workings.

English

Subject field(s)
  • Land Mines
DEF

A programmable or remotely controlled mine that is capable of being switched between standby and armed states one or more times. It is actuated by an electronic sensor device which cannot differentiate between friendly and enemy targets. It will consist of a single shot shaped charge, which may be contained in a launch projectile, and will be capable of top, horizontal or bottom attack. Most mines of this type will self-neutralise/destruct after a pre-selected period of time.

Key term(s)
  • third-generation mine

French

Domaine(s)
  • Mines terrestres
DEF

Mine programmable ou télécommandée qui peut être activée ou désactivée une ou plusieurs fois, et déclenchée par un dispositif de mise de feu qui ne peut distinguer les objectifs amis ou ennemis. Elle utilise une charge formée à coup unique qui peut être contenue dans un projectile, et qui agit par-dessus, par-dessous ou à l'horizontale. La plupart des mines de ce type s’autoneutralisent ou s’autodétruisent après une période prédéterminée.

OBS

mine de troisième génération : terme et définition uniformisés par le Groupe de travail de terminologie du génie.
