某铅锌矿的三维地质模型及储量估算

针对矿山现有的地质信息数据等，建立了以利用Surpac软件的三维地表模型、矿体模型及地质数据库，对矿山资源储量进行计算。基于地质统计学的理论，建立某铅锌矿地表模型、钻孔数据库、矿体模型、块体模型，对矿体内样品进行组合分析统计，采用幂次距离反比法对块体品位进行估值，最后根据国内对地质矿产资源的分类方法，按照不同边界品位、工业品位等分类依据，得出资源储量核实报告，为铅锌矿的后续生产，提供了可靠保证。结果表明：通过构建该矿地质数据库，建立的三维模型，可对地质工程、采矿工程、储量估算、矿石品位动态管理等提供技术支持。

Three dimensional Geological Model and Reserve Estimation of a Lead zinc Mine

For the existing geological survey data of a lead zinc mine,this paper carried out three dimensional geological modeling and resource reserve estimation for a lead zinc mine.Based on the theory of geostatistics,a ground model,a drilling database,an ore body model,and a block model of a lead zinc mine are established.The combined analysis and statistics of the samples in the ore body are used to estimate the block grade by the power distance inverse ratio method.Finally,according to the domestic classification method of geological mineral resources,and according to the classification of different grades,industrial grades,etc.,the resource reserve verification report is obtained,which provides a reliable guarantee for the follow up production of lead zinc mine.The application of surpac software provides convenience for mines in safe scheduling and mine information management.At the same time,it provides a more intuitive and effective method for calculating the depletion rate and loss rate in dynamic production.The research shows that:By constructing the mine geological database,the three dimensional model can provide technical support for mining engineering,geological engineering,reserve estimation,ore grade dynamic management.
