Abstract

Cette invention se rapporte à un explosif à base d'émulsion eau dans huile se caractérisant en ce qu'il contient un copolymère d'éthylène/acétate de vinyle. Il possède une excellente stabilité à long terme. Même lorsqu'il est conservé sous une charge pendant une longue période d'environ une année, cet explosif a moins tendance à subir une baisse de ses performances explosives et il ne se coagule que légèrement à un degré tel qu'il commence à contenir des coagulats partiels faiblement cohérents pouvant être facilement désagrégés. Même après un entreposage à long terme, le chargement avec cet explosif peut facilement être réalisé avec un chargeur. Dès lors que cet explosif possède une excellente résistance à l'eau, il est approprié également pour des explosions dans des points d'eau.
