| 摘 要： | 甲玛矿区位于西藏拉萨市区以东约61km处,属拉萨市墨竹工卡县甲玛乡和斯布乡（扎西岗乡）管辖。利用国产自主研发的Minexlporer软件,运用三维可视化和三维建模技术,对矿区深部及外围区域进行三维模型的建立。首先,通过搜集甲玛多源地质勘查资料进行数据库建设,利用3DEM矿体圈定原则——单工程矿体圈定、剖面矿体圈定、三维矿体圈定建立甲玛三维地质体模型。最后,利用地质统计学方法和传统储量计算法对甲玛矽卡岩型矿体进行储量计算。

| Abstract: | Jiama Mine is located in Maizhokunggar County, about 61 km away from the east of Lhasa of Tibet. By using the independent research and development of Minexplorer software, 3D visualization technology and 3D modeling technology, the authors set up a 3D modeling for the ore body in its deep and periphery. First of all, the authors constructed a database through collecting Jiama multi-source geological exploration data; then, established Jiama 3D geological model through following 3DEM ore body principles——ore body delineation in a drill, ore body delineation in profile and 3D ore body delineation. Finally, resource estimation for Jiama skarn-type ore body was made through using geological statistics method and traditional reserves calculation method. |
