摘要

为了研究深埋巷道围岩温度场的分布规律，基于传热学和渗流理论建立了深埋巷道围岩的热扩散数学模型，结合边界条件采用MATLAB对其进行了数值求解，获得了在风流和渗流耦合作用下围岩的温度场和温度矢量分布。研究结果表明，渗流改变了围岩初始温度场和温度矢量的对称分布的状态，围岩内部的温度场可划分为向内扩散区和向外扩散区。在围岩与风流的热交换作用下，巷道的壁面温度将接近风流温度，温度矢量零点的范围呈现出逐步增大的趋势。当热交换达到平衡状态时，向内扩散区的温度场呈现为环状对称分布状态；而向外扩散区等温线的形状没有明显的改变，但等温线的分布逐渐稀疏。

Abstract

In order to study the distribution rule of temperature field in surrounding rock of deeply buried roadways

the mathematical model of thermal diffusion is proposed based on heat transfer and seepage theory. Combined with boundary condition

the distribution of temperature field and temperature vector of surrounding rock under coupling airflow and seepage is obtained by using MATLAB. The results show that seepage changes symmetrical distribution of initial temperature field and vector

and the temperature field in surrounding rock may be divided into inward-diffusion area and out-diffusion area. When heat change between surrounding rock and airflow

wall temperature of roadways will approach to the temperature of airflow; and the scope of zero temperature vector will enlarge step by step. Temperature field of inward-diffusion area is annular and symmetrical distribution when heat change reaches balanced state; and the shape of isothermal curve in out-diffusion area doesn’t change obviously. At the same time

distribution of isothermal curves becomes rarefied.
