Mining practitioners from Australia, Canada, Germany, Britain, Scandinavia and the Russian Federation discussed the methods and practices of exploration, the problems of reconciliation and the use of geology information systems at the webinar attended by a large group of geologists from Russian, Kazakh, Kyrgyz and Ukrainian mining companies
Richard Burger of Mining Plus Australia shared his experience in analyzing the causes of unplanned dilution caused by the design process (mining or large block), incorrect assignment of bulk density or moisture, blasting methods (too large or small destruction or shear / swelling) or soil collapse.
Lyubov Egorova, Head of Geological Department, SRK Consulting (Russia) Ltd, used case studies to highlight the issue of comparing planned and actual indicators, which is relevant for many mining companies, and revealed in detail the methodology for constructing an operational model. Of particular interest to the webinar participants were the following sections of her report: general benchmarking of mining operations (ore reserves, volumes of declared ore reserves), comparison of indicators by tonnes, grade and metal from the forecast based on ore reserves, and actual development of balance ore reserves, as well as local comparative analysis (working areas: blocks, benches, mining areas, geological domains).
Latest geology information systems were discussed by Nornickel technical services, ESRI, Proxima, Sovzond and others.
Webinars on Mine Survey and Reconciliation and Exploration Geology for geologists will be held in the first quarter of 2022
