摘要:
为了方便快捷地求解采煤工作面围岩散热量，建立采煤工作面无因次围岩散热控制方程，采用有限体积法完成方程离散，基于Python编程平台编制数值模拟解算程序，剖析无因次围岩温度场演变规律，拟合不稳定换热准数与贝克莱数、毕渥数的回归关系式并开展现场验证。研究结果表明：采煤工作面围岩壁面不稳定换热准数随着采煤进刀呈现周期性变化，在进刀循环初始阶段围岩散热达到顶峰；不稳定换热准数与毕渥数和贝克莱数存在线性关系，据此拟合得到平均不稳定换热准数的回归方程；经现场实例验证，该回归方程计算值与实测结果的相对误差仅为2.65%，证明该方法具有形式简洁、精度高等特点。研究结果可为围岩散热量的快捷精准求解提供技术支撑。
Abstract:
In order to conveniently and quickly solve the heat dissipation of surrounding rock in the coal mining face,the dimensionless heat dissipation control equation of surrounding rock for the coal mining face is established.The finite volume method is adopted to complete equation discretization.A numerical simulation solution program is compiled based on the Python programming platform.The evolution law of dimensionless surrounding rock temperature field is analyzed,and the regression relationship between the unstable heat transfer criterion,Peclet number and Biot number is fitted,with on-site verification carried out.The research results indicate that the unstable heat transfer criterion on the surrounding rock wall of the coal mining face varies periodically with coal mining feeding,and the heat dissipation of surrounding rock reaches its peak at the initial stage of the feeding cycle.A linear relationship exists among the unstable heat transfer criterion,Biot number and Peclet number,on which the regression equation of the average unstable heat transfer criterion is fitted.Verified by field examples,the relative error between the calculated value of the regression equation and the measured result is only 2.65%,which proves that the method is provided with the characteristics of simple form and high accuracy.The research results can provide technical support for the rapid and accurate solution of surrounding rock heat dissipation.
