摘要以某水泥灰岩矿为研究对象，借助Surpac软件建立矿山地质数据库和三维地质模型，首先，基于地质统计学原理对勘探试样数据进行基本统计分析，通过空间插值方法，探究区域化变量与其他变量的空间自相关规律，建立样品变异函数结构模型；然后，利用普通克里格法对矿体品位进行估值；最后，采用基本统计和趋势分析方法对品位估值模型进行验证与评估。结果表明，利用普通克里格法所建矿体模型可靠，品位估值精度高，可为今后矿山资源合理开发利用提供科学依据。

Abstract: Taking a limestone quarry as the research object, the 3D geological deposit database and block model were built by Surpac software. Based on the principles of geostatistical analyst, the structure model of the reasonable variation function is built after basic statistical analysis and spatial autocorrelation of regionalized variable research through the spatial interpolation method. The grade and reserves of the deposit are estimated with the Ordinary Kriging method. Grade variation of the ore body in Z direction is drawn and used to verify and evaluate the model itself. The verifying result shows that the model is reliable and the estimation is relatively accurate which is structured and estimated by Ordinary Kriging. The Ordinary Kriging method can provide scientific grade estimation for the future development of the deposit.

Key words: limestone quarry 3D geological model ordinary kriging grade estimation model verify
