摘要
某铅锌矿床是内蒙古二连浩特—东乌珠穆沁旗多金属成矿带中的代表性矿床之一,成矿期经历了华力西期和燕山期的多期构造运动,断裂、褶皱的多次叠加使得该区地质情况复杂。为探讨估算该矿矿山地质储量,借助三维地质建模及可视化方式,可以直观而形象地对矿区进行研判。依据已有的地质勘探资料,在构建该铅锌矿地质数据库的基础上,运用三维地质建模技术建立了该铅锌矿的地表实体模型、巷道实体模型、矿体的实体模型及块体模型,并采用距离幂次反比法对块体模型进行了空间品位插值,对有用元素(铅、锌、银)进行了储量估算。
A lead-zinc deposit is one of the representative deposits in the Erlianhaote-Dongwuzhumuqiqi polymetallic metallogenic belt in Inner Mongolia.During the mineralization period,it experienced multi-phase tectonic movements in the Hualixi and Yanshanian periods,with many faults and folds.The secondary superposition makes the geological conditions of the area complicated.In order to explore the estimation of the geological reserves of the mine,the three-dimensional geological modeling and visualization methods can be used to visually and visually judge the mining area.Based on the existing geological exploration data,based on the geological database of the lead-zinc mine,the surface solid model,the tunnel solid model,the solid model of the ore body and the block model of the lead-zinc mine were established by using 3D geological modeling technology.The space model is interpolated by the power-inverse ratio method,and the reserves of useful elements(lead,zinc,silver)are estimated.
