兰坪铅锌矿架崖山矿段三维模型研究

兰坪铅锌矿是我国最大铅锌矿,对该矿山进行数字化意义重大。本文通过对兰坪铅锌矿架崖山矿段的各类数据进行分析研究,依据地质统计学原理和方法,采用自行编制的"矿床数学-经济模型"软件包和国外矿业软件Surpac,建立了该矿段的三维立体空间模型。实现了资料数据的动态查询、图形绘制、储量计算和矿体三维可视化等多项功能,极大地方便了矿山的生产管理。同时,三维模型直观地反映了矿体空间形态及分布特征,为矿山的探矿和采矿设计以及经济评价提供了科学的依据。

A study on the three-dimensional model of Jiayashan ore block in Lanping Pb-Zn deposit

The digitization of Lanping Pb-Zn deposit,the largest lead and zinc deposit in China,is of great sig-nificance.On the basis of the systematic analysis and research on various data of Jiayashan ore block in Lan-ping Pb-Zn deposit,and by applying principles and methods of geostatistics,this paper built the three-di-mensional space model of the ore block by “mathematic-economic model of deposit”software package crea-ted by the authors and mining software “Surpac”from a foreign company.The model has functions of dy-namic inquiry of data,graphic plotting,reserves calculation and 3D visualization of orebodies,which greatly facilitate the production management of the mines.Meanwhile,the three-dimensional model can intuitively reflect the spatial form and distribution characteristics of orebodies and can provide scientific basis for the de-sign of exploration and mining and economic evaluation of the mine.
