查询词典 mining

The paper gives a brief introduction on theory and means of orebed digitaled and interrelated mining software in domestic and international. On the basis of systematic analysis and research on Jiayashan ore segment, with the mathematic-economic model software bag developed by our library, via the special software Surpac and Micrmine, on the need of the Lanping Pb-Zn mine, the mathematic-economic model of the deposit has been established in Lanping pb-zn mine Jiayashan ore segment. Correlative important technological and economic guide lines have been analyzed and studied. At last, some fruits have been achieved:(1) For the first time, the mathematic-economic model of Lanpingpb-zn mine has been established , digitated and visualed of all kinds of useful information on ore body have been realized.

本文在对矿床数字化的理论与方法及相关的国内外矿业软件综述基础上，通过对该矿床的架崖山矿段地质特征进行充分分析和研究，运用自行研制的大型"矿床数学-经济模型软件包"，以国外矿业软件Surpac和Micrmine为辅助，结合兰坪铅锌矿矿山的实际需求，建立了兰坪铅锌矿架崖山矿段矿床数学经济模型，并对相关的重要技术经济指标进行了分析与研究，最终取得了如下成果：(1)首次在兰坪铅锌矿架崖山矿段建立了矿床数学-经济模型，实现了矿体各有用信息的数字化和可视化。
