Abstract

Procedimiento para preparar composiciones explosivas en lechada, caracterizado porque comprende las etapas de: (a) hidratar de 0,1 a 2% en peso de un espesante a base de un derivado sulfonado de goma guar en una mezcla de 30 a 90% en peso de una sal inorgánica suministradora de oxígeno y de 5 a 40% en peso de un disolvente o vehículo líquido a una temperatura elevada para reducir el tiempo de hidratación. (b) Ajustar el pH de la mezcla resultante a un valor de 3,1 a 5,5 ; y (c) Añadir el licor espesado resultante de 5 a 40% en peso de un combustible o combustible/sensibilizador sólido o líquido, junto con más sal inorgánica y, opcionalmente, con más espesante.
