摘要
随着金属矿山开采深度的增加,矿井高温热害问题会越来越严重,导致井下空气温度变化的主要因素是地热、空气压缩热、爆热和氧化反应热。文中分析了金属矿山井下热源及其危害,介绍了井下热量计算方法,提出利用矿井通风技术治理井下热害的措施。
With the increase of the depth of shafts in metal mine, the problem of high temperature heat-harm becomes more and more serious. The main causes are terrestrial heat, air compression heat, explosive heat and oxidizing reaction heat. The article analyses the heat sources in underground metal mines and heat-harm, and introduces methods to calculate the quantity of heat. The countermeasure of using ventilation technique to manage heat-harm in underground mines is put forward.
