| 摘 要： | 以高温矿井综采工作区为研究对象，对采空回填区、煤体-空气换热系统进行了二维数值模拟。计算结果表明，在空气初始温度为295.95 K，煤体、采空回填材料初始温度为313.15 K情况下，顺槽、工作面空气温度低于304.52 K，顺槽、工作面内空气与煤体、采空回填材料温差最小值为0.5 K。煤体、采空回填区的温度由初始值313.15 K降至299～314 K。进风顺槽、工作面、回风顺槽内的空气经过对流换热后的热量值在76.17～83.10 kJ/kg。在不考虑冲淡、排除顺槽、工作面有毒有害气体和粉尘，仅从降低顺槽、工作面内温度情况下考虑，采用雷诺数为13 808～276 170均能满足要求。以较小的动力损耗方面考虑采用雷诺数为69 040值以下为宜。从获得排除高温气体情况下考虑，采用雷诺数为69 040以上的条件。以上结论为矿井热害的综合治理提供了重要依据。
