【摘要】：为了探测自燃煤矸石山内部温度随时间和深度的变化情况,对煤矸石山的自燃深度和时间进行测算及预警。基于热传导理论模型,采用热源温度场迭加法解析自燃煤矸石山内部温度场。通过野外实际实验模拟,采用温度场模型对实验数据进行解析计算,得出结论:该模型适用于自燃煤矸石山内部温度场的解析计算,且计算简单,误差基本控制在10℃范围内,最大误差为20℃,模型精度较高,对自燃煤矸石山的火源位置探测及预警具有重要的指导意义。
[Abstract]:In order to detect the variation of internal temperature with time and depth, the spontaneous combustion depth and time of coal gangue mountain were measured and forecasted. Based on the theoretical model of heat conduction, the superposition method of heat source temperature field is used to analyze the internal temperature field of spontaneous combustion gangue mountain. Through the field experiment simulation, the temperature field model is used to analyze and calculate the experimental data. It is concluded that the model is suitable for the analytical calculation of the internal temperature field of the spontaneous combustion gangue mountain, and the calculation is simple and the error is basically controlled in the range of 10 鈩，
