Surpac软件在归来庄金矿深部矿床资源量估算中的研究和应用

归来庄金矿是目前鲁西南地区唯一的大型新类型碲金型金矿床，近几年深部找矿有了进展。在充分研究归来庄金矿成矿地质特征及金矿化类型的基础上，根据归来庄金矿深部的地质勘查工程资料,以Surpac系统软件为主要工具，首次建立了归来庄深部金矿床的地质数据库, 构建了矿体的三维可视化地质模型。基于归来庄金矿深部矿体三维模型，应用距离幂次反比法对归来庄金矿深部矿体估算了资源量。将估算结果和传统地质块断法进行对比研究，结果表明用此软件进行资源量估算简便且准确，可以为矿产开发提供依据。

Research and Application of Reserves Estimation Deep Part of Guilaizhuang Gold Deposit in Shandong Province Based on Surpac Software

Guilaizhuang gold deposit is the only large new type gold deposit in southwest of Shandong province. In recent years, it has made progress in ore prospecting in the deep part. On the basis of studying geological characteristics and gold mineralization types of Guilaizhuang gold mineralization ore bodies, according to previous geological surveying and engineering data of this deposit, regarding Surpac software as main tool, geological database of deep part deposit in Guilaizhuang gold deposit has been set up for the first time, and three-dimensional visualization geological model has been set up as well. Based on this model, by using Inverse distance weighted method, reserves of deep deposit have been estimated. Then compared with traditional geological block method. It is showed that reserves estimation based on Surpac software is simple and accurate. It can provide the bases for the development of mineral resources.
