部分矿山的热害治理可通过增加风量和其他非机械制冷降温措施达到理想的效果，风量的计算是此方法的关键。在传统矿井需风量计算方法的基础上，结合矿井热交换原理和矿井热源调查统计，针对矿山井下热害的特点建立矿井降温风量计算模型。该模型计算矿井降温风量的步骤包括：①需风量计算和风量分配；②选择主要风量路线；③分析计算井巷热源散热量；④计算采掘工作面干球温度；⑤计算分析采掘工作面干球温度随风量的变化情况；⑥确定矿井降温风量。将矿井降温风量计算模型应用于湖南某锑矿，计算出矿山的降温风量为78．88 m3/s。该矿井降温风量计算模型适用于其他类似矿山，具有一定的推广价值。

Heat-harm treatment in parts of the mine can achieve ideal effect by increasing the air flow and other non-me-chanical cooling measures,in which the key is to calculate the air volume. According to the characteristics of underground heat-harm and based on the traditional calculation of mine's demanded air flow,the calculation model of mine cooling air flow is es-tablished,which combined of the mine heat exchange principle and the mine heat sources investigation. In this model,the steps to calculate the mine cooling air flow are as following:①calculation of demanded air flow and the distribution of air flow;②se-lection of the main mine air flow route;③ calculation and analysis of the scattered heat source;④calculation of the dry bulb temperature at working Face;⑤ calculation and analysis of the variation of dry bulb temperature with the amount of the air flow;⑥determination of the mine cooling air flow. Then this calculation model is applied in certain antimony mine in Hunan to calculate the amount of cooling air as 78. 88 m3/s. The model has a certain value of popularization,which can be applied in other similar mines.
