摘　　要：在韦岗铁矿已知地热异常点周边约10 km^(2)实施地热资源调查与勘探,在分析区域重磁资料的基础上优选靶区,投入高精度重磁和广域电磁勘探获取深部地质结构,建立韦岗铁矿地热资源成因模型,基于靶区的地球物理勘探结果,选择同类地质构造部署地热探井,从“源、通、储、盖”等方面对地热探井进行预测。实践证明,基于老矿山已有地热异常“就矿找热”,在已知的地热成矿模型约束下投入勘探工作,具可行性和应用前景。Conducting a geothermal resource survey and exploration within a 10 km^(2) area surrounding the known geothermal anomaly points of Weigang Iron Mine,the study aims to optimize the target area through the analysis of regional gravity and magnetic data.Utilizing high-precision gravity and magnetic surveys,as well as wide area electromagnetic exploration techniques,deep geological structures are investigated to establish the genetic model of geothermal resources at Weigang Iron Mine.By identifying similar tectonic settings,geothermal exploration wells are strategically deployed based on the geophysical results from the target area,with predictions made regarding the geothermal exploration wells in terms of"source,circulation,storage,and cover".The efficacy of this approach is validated by the presence of existing geothermal anomalies in historical mines,demonstrating the feasibility and promise of conducting exploration within the framework of established geothermal mineralization models.
