| 中文摘要: |
| 文章以吉尔吉斯库鲁铜金矿床为研究对象,借助Surpac软件建立了矿区三维地质模型;基于地质统计学原理,对样品数据进行三参数对数转换后建立了变异函数结构模型;利用普通克里格和距离幂次反比法分别对矿床进行资源量估算,并以矿区的南矿体为例对估算结果进行分析,绘制矿体在不同方向上品位变化趋势曲线来对模型进行验证与评估。结果表明,采用Surpac软件所建模型可靠,估值精度较高,可为今后合理开发矿山资源提供科学依据。 |
| 英文摘要: |
| The Surpac software-based 3D geologfical model is built for Kuru Cu, Au mine in Kyrgyzstan. Based on geostatistics logarithmic conversion of three parameters of sample data is conducted then structure model of the reasonable variation function built. Mineral resource volume of the deposit is estimated with the ordinary Kriging method and distance power inverse ratio method. Estimation of the south ore body is analyzed. Grade variation curves of the ore body in different directions are drawn and are used to verify and evaluate the model. The result shows that the estimation is relatively accurate and the model is reliable and can provide scientific evidence for future development of the deposit. |
