Safety Evaluation of Emulsion Explosives Production Line based on SDG-HAZOP

SDG-HAZOP method was introduced into safety evaluation of emulsion explosives production line for the first time in order to conduct safety evaluation of emulsion explosives production process more effectively and to reduce accidents, Firstly, hazard factors in a typical production line of emulsion explosives were identified after analyzing the whole process. Then the key variables and relationship equations were listed based on evaluation unit division. SDG-HAZOP qualitative model was developed, by which automatic reasoning and analysis was conducted. The result could express almost all dangerous factors and adverse consequence, and can reveal the path of danger propagation. Finally, a safety evaluation system for emulsion explosives factories was built, which is practically significant to guide safety production.
