摘　　要：为提高黔东高地超大型锰矿资源量估算的精度和适用性,运用地质统计学法,借助QuantyPES软件,通过构建三维地质模型、建立样品数据库、统计分析、变异函数模型建立及克里金法估值等步骤,对锰矿品位的空间分布特性进行了研究。通过交叉验证,证实了所选计算参数的准确性,验证了变异函数模型的有效性。结果表明,地质统计学法估算的资源量与传统地质块段法估算结果基本吻合,误差极小,证明了地质统计学法在资源量估算中的准确性和可靠性。结论认为,地质统计学法减少了人为因素的干扰,提供了更为客观、准确的估算结果,有助于提升估算结果的可靠性,降低资源量估算的不确定性,为矿山规划和开采设计提供坚实的数据支持。To improve the accuracy and applicability of resource estimation for the super-large manganese mine in Eastern Guizhou Plateau,geostatistics was applied.With the aid of QuantyPES software,a series of steps including constructing a three-dimensional geological model,establishing a sample database,statistical analysis,variogram model establishment,and kriging estimation were carried out to study the spatial distribution characteristics of manganese ore grades.Cross-validation confirmed the accuracy of the selected calculation parameters and the effectiveness of the variogram model.The results showed that the resource estimation using geostatistics was basically consistent with the results obtained by the traditional geological block method,with minimal error,demonstrating the accuracy and reliability of geostatistics in resource estimation.The conclusion suggests that geostatistics reduces the interference of human factors,providing more objective and accurate estimation results,which helps to enhance the reliability of the estimation results,reduce the uncertainty of resource estimation,and provide solid data support for mine planning and mining design.
