摘　　要： 矿体的产状、形态复杂,用传统的方法很难准确、直观地了解矿体在三维空间的赋存状态。以东梁金矿为例,利用Micromine系统建立的矿区三维地质动态模型,直观、快捷、形象地显示了矿体的空间赋存状态及品位的分布情况,为矿体成矿规律的研究及下一步找矿提供信息。同时能够根据市场经济条件的变化,采用距离反比加权法,快速、可靠地进行资源/储量评估,产生的分类模型报告可以高效地提供每个标高范围内的资源/储量信息,及时为管理决策提供精准的地质信息服务,利于宏观管理。 While the occurrence and form of the ore body are complicated,it is difficult to determine the exact occurrence of the ore body in the three-dimensional space.In the case study of Dongliang gold deposit,the authors set up a dynamic 3Dgeological model of the mining area by using Micromine system.The model not only reflects the spatial occurrence and distribution of grades of the ore body in an intuitive,fast and vivid way,but also provides information for the research on metallogenic regularities of ore bodies and future prospecting works.Based on changes in market and economic conditions,the authors applied inverse distance weighting method to quickly acquire a reliable result of resource/reserve estimation,and the generated classification model report will effectively provide resource/reserve information in each elevation range and will be used as accurate and timely geological information service for decision-makers for the sake of macro-management.
