摘　　要：通过对井下热湿工程环境调查,分析三山岛金矿热害产生的根本原因。依据工程热湿环境调查结果,布设该矿围岩温度测试的测点位置,通过对不同中段相对应位置的温度曲线回归,得出三山岛金矿正常围岩温度梯度为2.2×10-2℃/m,受井下地热影响区域其地温梯度为2.6×10-2℃/m。通过对该矿不同热源进行分析,其围岩散热、机械设备、空气压缩及地热资源是致使三山岛金矿井下温度偏高的主要原因,该研究对类似矿山热源分析及其治理提供一定的基础数据。The engineering thermal and humid condition has been investigated to find out the basic reason of heat hazard at Sanshandao Gold Mine.According to the field investigation result of thermal circumstance,the position of surveying surrounding rockmass temperature is designed.Through the temperature curve regression at corresponding location of different middles,the normal surrounding rock temperature gradient is obtained as 2.2×10-2℃/m,and the geothermal gradient at underground geothermal area is 2.6×10-2℃/m.According to the analysis of different thermal resources,rockmass heat dissipation,equipment,air compression and geothermal resource are the main reasons leading to the temperature increasing at Sanshandao Gold Mine.The research provides a basic data for heat hazard analysis and its governance.
