摘要
针对矿井热害问题,在统计国内外矿井产生热害原因的基础之上,分析得到风流与围岩热交换及风流压缩放热是大多数矿井产生高温的主要因素.通过对巷道围岩温度场的解析和干燥巷道风温的预测,进一步指出了井下风流温度的分布规律,从而为制定矿井降温措施提供可靠的理论依据及必要的基础资料.
In order to overcome the problem of mine heat hazard,based on the statistical analysis on the underlying causes of mine heat hazard in the world,this study derives that the heat exchange between airflow and surrounding rock,and the heat generated by compressed airflow are main heat sources in most coal mines.Furthermore,the analysis on the temperature field of surrounding rock and the prediction of dry air temperature demonstrates the distribution characteristics of underground airflow temperature.The study provides a theoretical basis and an essential reference for taking countermeasure to cool the mine.
