摘要:
为了研究煤矿井下热源对巷道局部风流温度的影响，通过搭建实验平台以及建立数值模型，采用实验和数值模拟的方法，分析井下固定和移动热源对巷道局部风流温度的影响规律。研究结果表明：对比实验和数值模拟固定热源对巷道局部风流温度的影响，结果显示二者总体温度变化趋势一致性较好，验证了数学模型的正确性；井下热源移动速度不同时，顺风移动速度越大，对巷道局部温度影响越大，且巷道局部温度相对升高；逆风移动速度越大，对巷道局部温度影响越小，且巷道局部温度相对降低。
Abstract:
In order to study the influence of downhole heat source on the local airflow temperature of the roadway in coal mine, through establishing the experimental platform and the numerical model, the influence laws of downhole fixed and moving heat sources on the local airflow temperature of the roadway were analyzed by using the methods of experiment and numerical simulation. The results showed that for the influence of fixed heat source on the local airflow temperature of the roadway by the experiment and numerical simulation, the comparison results showed that both the overall temperature change trends had a better consistency, which verified the correctness of the mathematical model. When the moving speed of the downhole heat source was different, the greater the downwind moving speed, the greater the influence on the local temperature of the roadway, and the local temperature of the roadway increased relatively, while the greater the upwind moving speed, the smaller the influence on the local temperature of the roadway, and the local temperature of the roadway decreased relatively.
