Effect of Sodium Nitrate on the Incendivity of Explosives in Coal Dust-Gas-Air Mixtures

摘要

A series of gelatinous permissible explosives was prepared with increasing sodium nitrate content and subjected to an improved technique for evaluating incendivity in coal dust-air and coal dust-gas-air mixtures. Those explosives containing an appreciable amount of sodium nitrate were found to be very hazardous in coal dust-air and coal dust-gas-air mixtures. (Author)
