Abstract

Abstract:

In order to deeply study the explosion suppression process, parameter change, and practical application of various kinds of coal mine gas explosion suppressants, the types, action mechanism, and research methods of gas explosion suppressants in China and abroad were analyzed, and it is concluded that there are five kinds of explosion suppressants: inert gas, water mist, powder, porous medium, and halogenated hydrocarbon. The mechanism includes physical effects such as dilution of reactant concentration, decomposition and heat absorption of explosion suppressant, absorption of free radicals, and wave absorption and vibration reduction, as well as chemical effects such as consumption of key free radicals including hydrogen radical and hydroxyl radical. The synergistic suppression effect of N₂-water mist on flame propagation is better than that of CO₂-water mist, but the explosion suppression effect of CO₂is better than that of N₂ under the same conditions in terms of overpressure peak and pressure time history. On the basis of experiments, numerical simulation can show the development process of explosion suppression in real coal mine environments and make the turbulent disturbance and the quantity change of each free radical in the process of explosion suppression more detailed and specific. Finally, in the development of gas explosion suppressants, it is necessary to start with the elementary reaction of active free radicals such as hydrogen radical and hydroxyl radical, reduce its content, and delay the gas explosion process, so as to achieve the purpose of explosion suppression.

Key words: coal mine gas, numerical simulation, synergistic explosion suppression, active free radical, inert gases

粉体-细水雾	含钾化合物水雾、含钠化合物水雾^{[45⇓⇓-48]}	含钾化合物水雾比含钠化合物水雾的抑爆性能好,原因在于钾原子的活泼性比钠原子更强,更易于化学反应
多种协同抑爆	七氟丙烷/CO₂-超细水雾^[49]	试验与大涡模拟均证实,从压力变化、火焰结构、温度等角度来看,七氟丙烷/CO₂协同超细水雾的抑爆效果优于单种抑爆剂的抑爆效果
多种协同抑爆	CO₂-含钾盐添加剂的双流体细水雾^[50]	抑制效果随喷雾时间的延长而增强,峰值超压和火焰速度明显下降,火焰亮度降低甚至消失
