Abstract
Un método para prevenir las explosiones de polvo de sulfurodespués de una operación de detonación que involucren metales que contengan sulfuros CARACTERIZADO porque comprende:(a) cargar un agujero para explosión que ha sido taladrado en un cuerpo mineral que contiene sulfuros con un agente detonante emulsionante que contiene un emulsionante, una fase continua orgánica de combustible, de un agente de control de densidad y una fase discontínua de solución salina oxidante que contiene una sal oxidantes inorgánicas, agua que contiene urea en cantidades que van desde el 1% a 10% en el peso del agente explosivo, se carga el agente detonante en una relación de acople con el agujero; y(b) detonar el agente explosivo.Un método para prevenir las explosiones de polvo de sulfuro en operaciones de detonación que involucren metales que contengan sulfuros según la reivindicación 1 CARACTERIZADO porque comprende:cargar un agujero para explosión que ha sido taladrado en un cuerpo mineral que contiene sulfuros con un agente detonante emulsionante que contiene un emulsionante, una fase continua orgánica de combustible en cantidades de 3% a 12% en peso del agente detonante, un agente de control de densidad y una fase discontínua de solución salina oxidante que contiene una sal oxidante inorgánica en cantidades de 45% a 95%, agua en cantidades de 10% a 30%, y porque contiene urea en cantidades que van desde 1% a 10% en peso del agente explosivo, se carga el agente detonante en una relación de acople con el agujero; ydetonar el agente explosivo.
