Powdered emulsion explosive is a type of powdered ammonium nitrate explosive made with a low water content oxidant solution or fine molten oxidant droplets as the dispersed phase, and an oil-phase solution composed of specific carbonaceous fuel and emulsifier as the continuous phase. Under specific process conditions, it forms a water-in-oil emulsion matrix through intense shearing. This matrix is then processed into powder through methods such as spray drying, rotary flash evaporation, or cooling, solidification, and crushing. The rock-type product is widely used in rock blasting and various construction blasting operations, suitable for blasting projects without risks of gas or dust explosions. The coal mine permissible type is suitable for environments with risks of gas and coal dust explosions.
