摘要：

为探究铺设泡沫浆体隔热层对高温矿井围岩温度场的影响,利用傅里叶定律建立围岩-隔热层-巷道非稳态传热微分方程及泡沫浆体隔热层-巷道二维非稳态传热微分方程,运用有限差分法离散求解微分方程,以探究铺设泡沫浆体隔热层后的围岩温度变化及初始温度对泡沫浆体隔热层的影响。结果表明:由于泡沫浆体隔热层导热系数小,随着时间的变化,温度易趋于稳定;与泡沫浆体隔热层相邻的岩层间的温度差值较大,且泡沫浆体隔热层厚度越大岩体温度越高,可见铺设泡沫浆体隔热层阻碍了一定热量向巷道传递,使岩体温度梯度增加;当泡沫浆体隔热层初始温度更接近风流温度时,泡沫浆体内部温度变化梯度较小,可在较短时间内达到稳态。

Abstract:

In order to explore the influence of laying foam slurry insulation layer on the temperature field of surrounding rock in high temperature mines, the heat transfer differential equation of unsteady surrounding rock and the two-dimensional unsteady heat transfer differential equation of foam slurry insulation layer were established by using Fourier 's law. The finite difference method was used to solve the differential equations, so as to explore the temperature change of surrounding rock after laying the foam slurry insulation layer and the influence of initial temperature on foam slurry insulation layer. The results show that the temperature tends to be stable with time due to the small thermal conductivity of the foam slurry insulation layer. The temperature difference between the rock strata adjacent to the foam slurry insulation layer is large, and the larger the thickness of the foam slurry insulation layer, the higher the temperature of the rock mass. It can be seen that the laying of the foam slurry insulation layer hinders the transfer of a certain amount of heat to the roadway so that the temperature gradient of the rock mass increases. When the initial temperature of the foam slurry insulation layer is closer to the air flow temperature, the temperature gradient inside the foam slurry is smaller and the temperature can reach a steady state in a short time.
