Abstract

Patente de Invenção:<B>"DISPOSITIVO E MéTODO DE ENCHIMENTO PARA FUROS DE EXPLOSãO"<D>. Uma disposição de enchimento para um furo de explosão (1) possuindo pelo menos uma carga explosiva (3) no mesmo é descrita. A disposição de enchimento compreende um elemento esférico geralmente oco (4) disposto em uso no furo de explosão externamente à carga explosiva associada (3). A detonação da carga explosiva (3) deforma o elemento oco(4) de modo a bloquear substancialmente o buraco do furo de explosão (1) na localização do elemento oco (4) para impedir substancialmente a passagem externa suficientemente forte para permanecer substancial e funciolmente intacto depois da detonação da caga explosiva associada (3).
