摘要
介绍了作者采用热力模型,模拟有矿石放热的巷道型高温采场不稳定传热系数的研究方法和试验结果,并总结出不稳定传热系数及风湿风量的计算公式。
This paper describes the research method and results of the unsteady heattransfer coefficient in a high temperature drift-shape stope with heat dischargefrom ore dump based on a thermodynamic model made by the authors. The for-mulas for computation of the unsteady heat transfer coefficient and the air te-mperature and flowrate are also presented here.
