摘　　要：地质勘探对于资源开发具有不可或缺的重要性,准确的资源储量报告是体现勘查成果的核心环节,而基于三维地质建模和地质统计学的资源量估算方法受到了地勘行业一线技术人员的日益重视。依据2020年《固体矿产资源量估算规程》标准,本文详细阐述了使用3D Mine Plus矿业工程软件在现行规范要求下进行资源量估算的工作原理和流程,包括矿体实体模型构建、数据处理、变异函数分析、块体估值等关键环节。在新疆东戈壁钼矿床补充勘探报告中,利用矿区最新勘查数据,采用了与变异函数紧密结合的距离幂次反比法对资源量进行估算,并与传统的平行断面法估算结果进行了比较分析,二者矿石量、金属量、平均品位相对误差分别为5.81%、2.67%、3.67%。验证了3DMine Plus软件在资源量估算模块中的简便性和准确性,也证明了其在地质勘查和矿山生产管理等实际地质工作中的可靠性和实用性。In the geological prospecting industry,it pays a more and more important attention for front-line technicians to use the resource estimation method based on 3D geological modeling and geostatistics method for recently years,which attributing to geological exploration plays an indispensable role in resource development,and it is the fundamental aspect to reflect the exploration results for an accurate resource reserve report.This paper provides a comprehensive explanation of the operational principles and processes involved in utilizing 3D Mine Plus mining engineering software for resource estimation,adhering to the current regulatory requirements,which includes crucial steps such as constructing a solid model of the ore body,processing data,conducting variance function analysis,and performing block valuation,according to the standards set forth Solid Mineral Resources Estimation Regulations in the 2020.This study uses the latest exploration data in the supplementary exploration report of Donggebi Mo deposite in Xinjiang,in comparison with traditional parallel section method,employing the Inversed Distance Weighting method which is closely integrated with variance function analysis,the results reveal relative errors of 5.81%for ore content,2.67%for metal content,and 3.67%for average grade respectively.It can be concluded that the simplicity and accuracy of resource estimation module by using 3D Mine Plus software have been verified while its reliability and practicality in geological work such as geological exploration and mine production management have also been demonstrated.
