摘要
针对回采工作面围岩温度场和围岩散热难以计算的问题,研究了动坐标下的导热微分方程以及该方程的有限单元求解方法和计算式;以FORTRAN语言编制了计算程序并进行了实例计算。实例证明,该方法可快速准确地计算回采工作面的围岩散热。
In order to resolve the difficult problem to calculate the temperature of rock surrounding coal face andheat transfer between air and wall rock,the authors analyzed the heat conduction differential equation in movingcoordinate,resolved the equation by finite element method,set up the computer program with FORTRAN languageand calculated a actual coal face.lt is proved that the method in this paper can calculate the heat transfer betweenair and wall of rock rapidly and accurately.
