  • In order to prevent the hidden dangers of coal mine safety production brought by the application of static blasting technology, from the perspective of experiment, the mechanism of expansion and temperature rise of static expansive agent was analyzed, the temperature rise of static expansive agent under different conditions was verified, and its impact on coal spontaneous combustion was also analyzed. The results show that the static expansion agent is highly sensitive to water and has a strong exothermic ability after mixing with water, as the expansion agent and water are mixed in a volume ratio of 100:2, the maximum temperature after 2 h hydration reaction is 86.0 ℃, and the heat release increases with the proportion of water increases. Exothermic expansion agent enhances the oxidation activity of coal and shortens the spontaneous combustion period of coal.
