Micromine软件在矿床三维建模及资源量估算中的应用--以喀麦隆洛比铁矿为例

以喀麦隆洛比铁矿为例,运用 Micromine三维矿山软件的三维显示功能,对矿体进行了三维立体展示,直观地显示了该矿体的空间分布特征。在此基础上,分别运用Micromine软件的距离反比加权法和封闭多面体法进行了资源量的估算,并与传统方法(块段法)储量估算的结果进行对比,三者相对误差较小,为0.03%和6.75%,符合规范要求,进一步验证了Micromine软件在矿山资源量预测中的可靠性。

Micromine Software Application on 3D Modeling and Resource Estimate in the Ferrum Desposit:An Example from Cameroon Lobi Iron Deposit

Taking Cameroon Lobi iron deposit for example, the authors show the three-dimensional ore body to display its space distribution directly with the Micromine software. On this basis the cubic inverse distance meth-od and closed polyhedral estimation method are used for estimating the reserves of the ore body. Compared the re-sults from the traditional method (section method), the relative error among the three methods is small, and the relative errors are 0.03%and 6.75%, which meets the requirements of the specification, and further verifies the re-liability of the Micromine software in the prediction of mining resources.
