ABSTRACT
The thermal stability of the existing three level coal permitted water gel explosive in our country is good [Wang, Ma, Liu, 2007]. However, large quantities of inhibitor marble powder in the explosives decrease explosion energy greatly, which makes gradually reduces the ability of explosives satisfy the actual requirement [Han, 2009]. Sodium chloride was used as an inhibitor in order to improve explosion properties of explosives in the experiment because its chemical restraining efficiency is higher than marble [Zhao, 2007]. Water gel explosive would decompose under thermal energy, and in rising temperatures, this decomposition would turn more severe [Wang, 1985]. Thus, it becomes crucial for research to investigate whether or not the addition of the inhibitor sodium chloride can keep quondam excellent thermal stability. It is thus very important to research the thermal decomposition character of new coal permitted water gel explosives.
