| 中文摘要: |
| 三维地质建模的成功是深部找矿预测与储量估算的关键,文章利用国产3DMine矿业工程软件系统,整理并数字化了石人嶂矿区大量的地质勘探资料,针对矿区深部钨矿脉纤细、簇型分布等特点,改革传统的矿体圈定方法,探索并建立了石人嶂钨矿的地层模型、构造模型、矿体模型、地质工程模型等,实现了矿区深部数据的三维可视化。经反复计算校验,结果表明:在矿体的块体模型中依据采样点的品位信息采用距离幂次反比的估算方法对资源储量估算更为合理。石人嶂钨矿的三维地质综合模型对揭示矿区成矿规律、形象地选择矿体精确便捷的储量估值方法、深刻了解地质体的空间位置关系都至关重要,并能为矿产勘查及工程规划等提供科学依据。 |

| The success of the three-dimensional geological model is key for the deep prospecting prediction and reserves estimation. This paper demonstrated the application of the domestic 3DMine engineering software system in aspects of constructing 3D geological model and reserve estimation for the Shirenzhang tungsten deposit. A large amount of exploration data were digitized and input for constructing database. Considering the spatial forms of the tungsten orebodies as thin veins and cluster distribution, the authors adjust the traditional method of delineating the tungsten orebodies, and establish strata model, structural model, orebody model and geological engineering model of the Shirenzhang deposit respectively, and finally realize the 3D visualization for the deep exploration data. Through multiple calculation and calibration, it is concluded that the estimated reserves in the block model by the Power Inverse Distance method is much more reasonable based on the obtained sampling grade information The construction of the integrated 3D geological model of Shirenzhang tungsten deposit is the key to reveal the metallogenic regulations, to select the accurate and convenient method for the reserves estimation, and to understand the spatial relationship of the geological bodies as well as provide a scientific basisfor further mineral exploration and engineering planning. |
