基于3DSuffer的矿区深部关键界面特征

The Characteristics of Deep Pivotal Stereographs Based on 3DSuffer in Longqiao Iron Deposit

文中系统统计了庐江-枞阳矿集区龙桥铁矿区地表高程及深部矿体顶板、底板、火山岩底面、正长岩顶面矿石品位变化规律;以3DSuffer为基础,得到关键界面的3D图示。其中矿区地表高程变化明显反映了陆相火山岩边界和下伏侏罗系砂岩的接触界面;矿区深部矿体顶板、火山岩底、矿体底板和正长岩顶面的产状与地表出露的侏罗系砂岩不完全一致;矿石平均品位变化规律矿区南部高于北部。这些关键界面特征的获得为矿体开采、矿体深部构造特征及勘探提供了直观鲜明的数据信息。

In this paper, it＇s systemic statistical the change rules on surface elevation, roof and footwall of ore bodies, underside of volcanic rocks, superface of syenite and variation in grade of ores in deep of Longqiao iron deposit in Lujiang - Zongyang ore concentrated area, and draw corresponding pivotal stereographs on basis of the 3DSuffcr software. The change of surface elevation obviously reflect the contacted borders between the Cretaceous continental volcanic rocks and Jurassic sandstone, the occurrences are incompletely unanimous among the roof and footwaU of ore bodies, underside of volcanic rocks, superfaee of syenite and the exposed bedding plane of the Jurassic sandstone. The average variation in grade of ores indicated the grade of the south is higher than the north ones. All these information of key surfaces will provide intuitionistic and distinctive deep data for mining, researching the characteristics of deep structure on ore bodies and prospecting.
