| Abstract: | Physical and chemical properties of rice husk powder and wood powder were analyzed. Being additives in expanded ammonium nitrate (AN) explosive, rice husk powder was used as the substitute of wood powder. Combining the demand of cost reduction and efficiency increase of manufacturing factory, the optimum test scheme of rice husk powder as combustible agent was obtained. In this scheme, cartridge density of expanded AN explosive increases from 0.85 g/cm3 to 0.94 g/cm3, harmful gas content reduces from 68 L/kg to 59 L/kg, detonation velocity increases from 3 400 m/s to 3 480 m/s, and sympathetic detonation distance increases from 5 cm to 7 cm. |
