This paper introduces the "5.20" of the emulsion explosive incident and analysis the cause of the accident. Based on the production of explosion accident summarizes the security problems of emulsion explosive production process, and relevant measures are put forward. Combining the decomposition mechanism of ammonium nitrate in the emulsion explosives and the lessons from the production of emulsion explosives explosion, the conditions of the emulsion explosives (matrix) thermal decomposition in the emulsifier are given that are the formation of hot spot and the accumulation of heat. Then the factors of hot spots generated in the production of emulsion explosives and the occurred conditions of the heat accumulation are analyzed and summarized.

Cause Analysis

Emulsion explosive have well frost resistance, it can be stably detonated at -300C. But there are many misfires occurred in blasting construction of shaft frozen zone. After analysis, the causes was water in the hole frozen and it’s volume increased, so explosive cartridge was pressed, it’s density enlarged, and misfire created when it’s density exceed critical density of stable detonation. Based on analysis, plastic tube casing charge adopted for construction, and prevent misfire effectively.
