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. 7, record 1, English, - rock%20burst
Record number: 1, Textual support number: 1 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. 8, record 1, English, - rock%20burst
Record number: 1, Textual support number: 1 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. 4, record 1, English, - rock%20burst
Record number: 1, Textual support number: 2 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. 4, record 1, English, - rock%20burst

La forme la plus courante de dispositif anticouple est un petit rotor, semblable à une hélice d'avion, monté à la queue de l'hélicoptère sur un arbre orienté perpendiculairement sur un côté, de manière à repousser la queue latéralement; ce rotor est souvent caréné (fenestron). D'autres appareils utilisent un jet d'air comprimé éjecté latéralement en bout de queue, ce qui supprime les pièces en mouvement et l'arbre de transmission de queue. 2, record 3, French, - jet%20d%27air

[Powder snow] avalanches composed of dry snow usually generate a dust cloud as the sliding snow is whirled into the air ... Their speed may exceed 200 km/hr. ... Under certain circumstances, enough snow crystals are mixed with the air to form an aerosol which behaves as a sharply bounded body of dense gas rushing down the slope ahead of the sliding snow. This wind blast can inflict heavy destruction well beyond the normal bounds of the avalanche track. 8, record 4, English, - air%20blast

Some slides, particularly large ones, appear to be preceded by an air blast or pressure wave. Destructive air blasts are not common. However, there are certain paths where the phenomena occurs regularly. When it does occur the air blast may extend about 100 meters beyond a major path. 5, record 4, English, - air%20blast

Une avalanche en aérosol est un écoulement turbulent résultant de la suspension de particules de neige dans l'air, il ressemble à un gros nuage de neige se déplaçant à très grande vitesse. Il est précédé d'environ une centaine de mètres par un écoulement d'air (sans entraînement de cristaux) appelé vent ou souffle de l'avalanche. La pression de ce souffle est faible, de l'ordre de 5 kN/m², mais peut être suffisant pour provoquer des dégâts (arbres, toitures, etc.). 4, record 4, French, - vent%20d%27avalanche
