Temperature Raising Analysis of Emulsion Explosive in Blast Holes at High Temperature
摘要
Abstract
In order to obtain the internal temperature distribution of the emulsion explosive in blast hole at high tem-peratures, the thermocouple temperature measurement technology was applied to measure the inner temperatures (different positions) of the emulsion explosive. The results show that the temperature of the emulsion explosive was lower than that of water and the internal temperature-history curve of the emulsion explosive can be better described by an exponential func-tion. The change of temperature-history curve of outer emulsion explosive is in accordance with the change of temperature-history curve of water, and the inner temperature is relatively lower, which shows the outer of the emulsion explosives are affected by the environmental temperature. The inner temperature rise rate of emulsion explosive is relatively slow because of the water-in-oil structure and specific endothermic action of ammonium nitrate. It is advantageous for emulsion explosive under protection to be used in the fire area at high temperatures.关键词
