| 中文摘要: |
| 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.文中以相山矿田横涧-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。 |
| 英文摘要: |
| 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 combining with the experiences of mineral resources exploration and mining. As a result, 3 favorable places for prospecting were delineated using the method of prospecting information. Results show that the deep subsurface of Hengjian-Gangshangying mining area has a large prospecting potential. |
