摘　　要：三山岛金矿深部热害是亟待解决的问题。F3断裂影响区域内的低温热水对金矿深部热害的贡献不可小觑。本文主要根据矿山深部巷道涌水点长期监测的温度变化特征,分析了矿山地表冷水体和深部热水体的渗流影响范围。在F3断裂带聚热机制下,涌水温度与巷道气温良好的线性关系,很好地表明了深部低温热水对巷道气温的控制作用。这种规律性的认识能够指导矿山下一步的深部开拓设计和热害防治。How to eliminate heat harm in the deep of Sanshandao Gold Mine is very urgent. The low-temperature geothermal water going up through the F3 fault zone contributes to the heat and water disasters. The present paper revealed the seepage scope of cold water from surface and warm water from deep of the gold mine with the help of the monitored temperature variability of water inflowing into level drifts for long time. By the thermal trap mechanism of the F3 fault zone,good linear relations between inrushing water and level drift temperatures showed the control response in level drift temperatures to the geothermal water temperatures. This regular knowledge can guide to make next excavation designs and heat harm control countermeasures.
