A New Standard-oriented Three-dimensional Mine Resource Reserve Evaluation System
In order to address the issues of resource reserve data connection and transformation,as well as the inapplica-bility of the original reserve evaluation method caused by the release of the Classification Standard for Solid Mineral Resource Reserves(GB/T 17766-2020),a new system for resource reserve evaluation of mining enterprises based on 3D mining software has been constructed.On the basis of analyzing the characteristics and changes of the new classification standards,this paper sorts out the digital evaluation process of resource reserves in mining enterprises,establishes a resource reserve classification transformation model based on the corresponding relationship between the new and old standards,and uses mining software to update resource reserve data.The reserve estimation method matching the new classification method is studied and the geolog-ical resource modeling is completed.The resource allocation criteria in the three-dimensional environment is proposed,and the transition from the old standard to the new standard is completed and the interpretation and application of the new standard is completed.The comprehensive upgrade of the resource reserve evaluation model is realized.Based on the geological resource data of a metal underground mine in Shandong Province,a systematic verification was carried out,and historical data updates and comprehensive evaluation of newly added resource reserves were achieved using mining software.The study results show that the new standard reserve management system constructed in this paper has achieved information management of reserves in the context of modern mining standard changes from two aspects of the transition between new and old standards and the inter-pretation and application of new standards,providing reference for other similar metal underground mines.
