三维地质模拟在深部找矿勘探中的应用

我国矿产资源形势严峻,使深部找矿勘探工作的重要性大大提高。三维地质模拟作为一种新型有效技术,利用立体建模的方式建立矿床三维模型,可定量定位地表达各种地质信息,有效地恢复矿区的深部与浅部的构造形态,这些地质信息共同存在于相同的三维空间中,受钻孔等直接信息数据的约束,更接近现实世界。本文论述了三维地质模拟在深部找矿工作中的广泛应用,包括深部矿床等地质体建模、综合分析、多种图件的自动绘制等,可为矿床储量估算、成矿规律总结、深部成矿预测和矿山生产等工作提供直观、快速的数据和技术支持。

APPLICATON OF 3D GEOLOGICAL SIMULATION IN DEEP ORE EXPLORATION

Grim situation in the sector of mineral resources has greatly reinforced the importance of deep ore exploration in China.As a new effective technology,3D geological simulation that models an ore deposit in three dimensions can express various geological information quantitatively and positionally,effectively rebuild structural form of a mine at both deep and shallow level.All such geological information coexists in same 3D space and is confined by borehole and other direct information data,therefore more being close to the actuality.This paper described wide applications of 3D geological simulation in deep ore exploration,including deep ore body modeling,integrated analysis,automatic generation of a variety of graphs,which can provide visual and quick data and technique in support of ore deposit reserve estimate,metallogenic law summarization,deep metallogenic prognosis and mine production.
