摘要 本文以焦家金成矿带矿区为研究对象,通过收集矿区钻孔及测温孔资料,利用Comsol数值模拟软件,对矿区部分区域的地温场进行三维数值模拟。结果表明:地温模拟值与实测值的相对平均误差为4.92%,相关系数在0.99以上,与实际情况基本吻合。此外还探讨了人为抽水对地温场的影响,为矿区的开采和热害防治提供参考依据。 In this paper,the mining area of Jiaojia gold mine as the research object,through the collection of mining drilling and temperature hole data,using COMSOL numerical simulation software,the 3D numerical simulation of the temperature field in some areas of the mining area.The results show that the relative average error between the simulated and measured ground temperature is 4.92%,and the correlation coefficient is above 0.99,which is basically consistent with the actual situation.In addition,the influence of artificial water pumping on geothermal field is also discussed,which provides reference for mining and heat damage prevention and control in mining area.
