In order to ensure security in production process for the HNS explosive, emphasize security analysis from the explosive properties, the charging technological procedure and parameter, the designing and using of pressing mold. The result shows that the HNS explosive pressure charging technology is safe and reliable. Through the simulation analysis of pressing mold blasting and the safety experiment of shelter in the equipment, the conclusion comes that even if the exploding happened, during the technological procedure, the technology condition, at the present, it could also effetely ensure the security of the workers.
