摘　　要：在深部找矿过程中,三维地质建模技术起着不可或缺的作用。本次研究以相山矿田横涧-岗上英矿区为例,依托成矿理论、成矿预测理论和矿产资源勘查与评价理论,分析总结横涧-岗上英矿区的成矿地质条件,利用三维地质建模软件GoCAD建立研究区的地形、地层、构造、岩体、矿体和钻探模型,进一步结合勘查开采经验,建立矿区的地质找矿模型,并且采用找矿信息量法圈定成矿有利区段3处。结果表明,横涧-岗上英矿区深部仍有较大的找矿潜力。3D geological modeling technology plays an indispensable role in the process of prospecting at depth. This work analyzed the geological conditions of the Hengjian-Gangshangying mining area in the Xiangshan ore field based on the theories of metallogenic,prediction,mineral resources exploration and evaluation. The models of topography,strata,structure,rock-bodies,ore-bodies and drilling were established by the 3D geological modeling software—GoCAD and a geological prospecting model was also built combined with the experiences of mineral resources exploration and mining. As a result,three favorable places for prospecting were delineated using the method of prospecting information. Results show that the deep subsurface of the Hengjian-Gangshangying mining area has a large prospecting potential.
