随着矿山开采深度增加，原岩温度亦不断升高，围岩放热是深部矿体热环境恶化的诱因之一，严重制约深部矿体的安全高效开采。为有效分析三山岛金矿深部巷道围岩热源灾害诱因，本文通过在三山岛不同中段现场钻取岩样，在实验室内进行加工，应用稳态法测试岩石放热系数，测试结果表明：围岩的热传导系数随地点不同亦有一定的差异，三山岛金矿岩石的平均热传导率为1．92，围岩的平均热传导率为1．79，借此可以分析围岩放热量，为深部降温提供基础数据。
隨著礦山開採深度增加，原巖溫度亦不斷升高，圍巖放熱是深部礦體熱環境噁化的誘因之一，嚴重製約深部礦體的安全高效開採。為有效分析三山島金礦深部巷道圍巖熱源災害誘因，本文通過在三山島不同中段現場鑽取巖樣，在實驗室內進行加工，應用穩態法測試巖石放熱繫數，測試結果錶明：圍巖的熱傳導繫數隨地點不同亦有一定的差異，三山島金礦巖石的平均熱傳導率為1．92，圍巖的平均熱傳導率為1．79，藉此可以分析圍巖放熱量，為深部降溫提供基礎數據。

With the increase of mining depth,the original rock temperatures are rising.The heat release of surrounding rock is one of the causes of environmental degradation in deep mining,which restrict mining of deep ore body safely and efficiently.For effectively analyzing of heat disaster inducement of deep road-way surrounding rock in sanshandao gold mine,the rock samples drilled in Sanshandao gold mine from dif-ferent middle field were processed in the laboratory,by using steady-state method the thermal conductivi-ty of the rock is testified.Test results show that the thermal conductivity of rocks has certain difference for various locations,the average thermal conductivity of the ore is 1.92 and the average thermal conduc-tivity of the surrounding rock is 1.79.Based on these,the heat release can be analyzed and provide basic data for deep refrigeration.
