兰坪铅锌矿架崖山矿段三维模型研究

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

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。

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 ＂Surpae＂ 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.
