为探求新型有效阻隔瓦斯爆炸装置,研究适合煤矿使用的阻隔爆材料,利用自行设计制作的30 cm×30 cm方形实验管道进行瓦斯爆炸实验研究工作。文中测试放置0.3 g/cm3泡沫铁镍金属材料后的管道火焰温度数据,并结合火焰大小,共同作为判定该材料对爆炸波能量控制能力的指标。实验表明,0.3 g/cm3泡沫铁镍金属具有抑制瓦斯爆炸火焰波的作用和较强的阻火能力,对管道内瓦斯爆炸火焰温度最大衰减率在7.1%~70.7%之间。研究发现,厚度、孔径及基体材料成分对火焰波的抑制效果存在一定的影响,厚度大、孔径小、含镍成分高的多孔泡沫铁镍金属材料有利于火焰波的衰减。

In this paper, by using self-designed 30cm×30cm square piping experimental study on gas explosion, the new and effective gas explosive device was explored, and the barrier burst material suita-ble for use in coal mines was studied. In the tests, density of 0.3 g/cm3 foam iron-nickel metal materials were placed in the pipe, and the flame temperature data and flame size were considered together as the judgment of the target material on the explosive wave energy control. The experiment results show that 0.3g/cm3 bubble iron-nickel metal have the inhibitory effect of gas explosion flame wave and strong fire resistant capacity, and the maximum decay rate of gas explosion flame temperature in the pipe is be-tween 7.1~70.7%. Studies have also found that the thickness, diameter and substrate material composi-tion have certain influences on the inhibition effect of flame wave, and the porous foamed iron-nickel metal with high thickness, small aperture, and high nickel-containing compositions is favorable for the flame wave attenuation.
