| 摘 要： | 攀枝花铁矿属于基性岩浆侵入晚期分异型矿床，其地质环境极其复杂。采用3DMine矿业软件作为平台，对攀枝花尖山矿区地质勘探资料进行全面整理并建库，针对矿区深部铁矿体具有韵律性、顺岩层、单斜产出等特点，改变传统矿体圈定方法，从新的角度探索并建立了尖山矿区的地表模型、构造模型、矿体模型、矿带模型、地质工程模型等，实现了地质体的三维可视化。基于矿体的块体模型、依据采样点的品位信息空间分布形态而采用改进的克里格估算方法，对矿区铁矿储量的估算更为合理。

| Abstract: | Panzhihua iron deposit belongs to the intrusive magmatic ore deposits in late differentiation , and the geological environment is extremely complex.By 3DMine mining engineering software Panzhihua Jianshan min-ing area geological exploration database is constructed . For deep mining iron ore body with rhythm , smooth rock, monoclinic output characteristics, the traditional ore delineation method is changed from a new perspec-tive, in exploring and establishing the Jianshan mining area surface model, structure model, ore body model, ore belt model, geological model, by 3D visualization of mining area.The estimation method is established based on the block model of ore sampling points.The improved Kriging for grade information of mining area is more reasonable. |
