为防止煤矿井下瓦斯煤尘爆炸,研制无电源触发式抑爆装置。在地下试验巷道中进行的瓦斯煤尘爆炸抑爆试验表明,无电源触发式抑爆装置能在距爆源45m内扑灭火焰,抑制爆炸。该装置能现场使用、维护方便、成本低,可在较近距离抑制爆炸传播,结合了被动、自动隔抑爆装置的优点,比现有技术有更好的推广应用前景。
In order to prevent coal mine gas explosion, the development of non-power triggering explosion suppression device. The test of gas explosion in underground coal mine dust explosion test shows that no power triggering explosion suppression device can extinguish the flame within 45m from the explosion source and suppress the explosion. The device can be used on site, easy to maintain, low in cost and can inhibit the propagation of explosions at a relatively close distance, combining the advantages of passive and automatic antiknock devices, and has better popularization and application prospects than the prior art.
