Ore Quantity Calculation Method Based on 3D Visualization Modeling Technology

以新疆乔普卡铁矿为例,采用RTK GPS测量系统并结合MapGIS、AutoCAD、3DMine等软件,对矿量三维可视化计算方法进行了研究。首先采用RTK GPS测量系统对地表进行三维精密定位,测出采区的矿体界限;然后以地质详查资料为依据,运用MapGIS、AutoCAD、3DMine等软件构建矿体三维模型,从而准确地获取矿体分布及体积,进而计算出的可采矿量。结果表明,该方法计算出的矿量较传统方法而言精度较高,快速且直观。

Taking the Qiaopuka iron mine of Xinjiang as an example, the 3 D visualization technology ore calculation method is researched based on RTK GPS measurement system, MapGIS, AutoCAD and 3DMine software. Firstly, the RTK GPS measurement system is adopted to conduct 3D precision positio- ning so as to obtain the ore boundaries of mining area. Then, according to the detailed survey of geolog- ical data, the orebody 3D model is established by adopting the MapGIS,AutoCAD, 3DMine software to obtain the distribution situation and volume of orebody accurately to calculate the minable quantity. The research results show that, the ore quantity calculation method with the characteristics of high precision, quick and intuitive is superior to the classical methods.
