摘要:
防灭火泡沫材料是1种新型的防灭火材料,对高位倾斜裂隙火灾的降温隔热、充填加固具有很好的应用性能。为了了解高位倾斜裂隙通道中泡沫流体的扩散规律,通过理论推导得出不同裂隙倾角和方位角下浆体2端面压力差随时间的变化方程式,以理论公式为基础进行修正,提出了泡沫流体的扩散规律函数式,并通过用其他实验测点进行误差对比分析。研究结果表明:误差均在允许的范围之内,证明拟合出的函数式具有普遍适用性,可以为大采空区隐蔽高温火源点的防治提供理论支持。
Abstract:
The inorganic solidified foam material is a new type of material for fire prevention and extinguishing, which has the good application performance for the cooling, heat insulation and filling reinforcement of fire in the highlevel inclined fissure. In order to understand the diffusion laws of foam fluid in the highlevel inclined fissure channels, the equation of the pressure difference between the two sides of slurry changing with time under different dip angles and azimuth angles of fissure was obtained through the theoretical derivation, and the correction was carried out based on the theoretical formula. The function formula about the diffusion laws of foam fluid was put forward, and the error comparison analysis was carried out through using other experimental monitoring points. The results showed that all the error were within the allowable range, which proved that the fitting function formula has the universal applicability, and it can provide the theoretical support for the prevention and control of hidden fire source points with high temperature in the large goaf.
