Buffer Blasting. Buffer blasting is possibly the most simple method of control blasting and involves a modification to the last row of the main blast pattern. Modifications are limited to reduced burden, spacing, and explosive loads. The aim is to limit ground shock from the blast. The method is usually employed in conjunction with some other control blasting technique, such as pre-splitting, and its results are quite economical. Buffer blasting can only be used by itself when the ground is fairly competent. It may produce minor crest fracturing or backbreak but the amount of damage is less than would be produced by the main production blast if no control blasting was used at all.  2, record 1, English, - buffer%20blasting

Dynamitage contrôlé. Le dynamitage contrôlé est une méthode spécialisée qui vise à minimiser les effets indésirables du dynamitage, tels que les vibrations du sol, la surpression de l'air et les projections de pierres. Les techniques incluses dans le dynamitage contrôlé sont le forage en ligne, le dynamitage en douceur (contour ou périmètre), le pré-fendage, le dynamitage tampon et le post dynamitage. Le dynamitage contrôlé est particulièrement utile dans les zones peuplées ou sensibles où les dommages aux structures environnantes et à la sécurité des personnes doivent être soigneusement gérés.  1, record 1, French, - dynamitage%20tampon

An excavated or natural channel, usually removed some distance from a dam, provided to permit the release of extraordinary flood flows or flood discharge beyond the capacity of the service spillway. Control is seldom furnished and a low embankment of earth may be used to allow the water surface of the reservoir to rise above the crest of the emergency spillway. If continued inflow causes overtopping of the embankment plug, it is intended that the plug shall wash away, releasing the excess water without endangering the main dam.  4, record 2, English, - emergency%20spillway

Canal creusé ou naturel, d'habitude éloigné à une certaine distance d'un barrage, prévu pour permettre la décharge de débits de crue exceptionnels dépassant la capacité de l'évacuateur de service non restreint. Son réglage est rarement prévu et une basse digue en terre peut être utilisée pour permettre à la surface d'eau de la retenue de monter au-dessus de la crête de l'évacuateur de secours. Si l'arrivée continue d'eau entraîne la submersion de la digue fusible, on compte que celle-ci sera emportée par l'eau, laissant échapper l'eau excédentaire sans mettre en danger le barrage principal.  4, record 2, French, - %C3%A9vacuateur%20de%20secours

The military crest... is the point near the top of a slope or brow from which the entire slope below can be seen. This strategic vantage point has historically been vital for an army's control and defense of the high point and surrounding countryside(hence its name). The military crest is also a desirable building location because of the view it affords.... Furthermore, the military crest is an important point for locating structures that visually blend in with the landform.  3, record 3, English, - military%20crest

The top of the slope is most exposed to the elements.
