Abstract

SE REFIERE A UN METODO PARA REDUCIR LA FORMACION DE OXIDOS DE NITROGENO EN HUMOS POST-EXPLOSION RESULTANTES DE LA DETONACION DE UN EXPLOSIVO EMULSIFICADO, EL METODO COMPRENDE UN EXPLOSIVO EMULSIFICADO (EMULSION AGUA EN ACEITE, QUE COMPRENDE DE 0,2% A 5% DE UN EMULSIFICADOR) CON UN CONTENIDO DE HASTA 80% DE ANFO, UNA FASE CONTINUA DE COMBUSTIBLE ORGANICO INMISCIBLE (DE 3% A 12% EN PESO DE LA COMPOSICION), Y UNA FASE DISCONTINUA DE SOLUCION SALINA OXIDANTE QUE COMPRENDE UNA SAL INORGANICA OXIDANTE, PREFERIBLEMENTE NITRATO DE AMONIO, AGUA O UN LIQUIDO MISCIBLE EN AGUA, CARACTERIZADO POR EL USO EN LA FASE DISCONTINUA DE ALREDEDOR DE 5% A 30% EN PESO DEL EXPLOSIVO DE UREA, PREFERIBLEMENTE DE 5% A ALREDEDOR DE 20%; PUEDE CONTENER ADEMAS DE 20% A 50% DE GRANULOS DE NITRATO DE AMONIO; ESTE METODO TRABAJA PARTICULARMENTE BIEN CON DISENOS EXPLOSIVOS QUE USAN MECHAS EN AREAS EXPLOSIVAS SUSCEPTIBLES A LA FORMACION DE OXIDOS TOXICOS DE NITROGENO
