1 引言
《新的监管环境下矿产资源及其不确定性的地质统计学评价(Geostatistical Evaluation of Mineral Resources and Their Uncertainty Under the New Regulatory Environment)》短期课程将于2022年9月26~30日在加拿大麦吉尔大学(McGill University)采矿和材料工程系开班授课,课程指导老师是加拿大SRK Consulting的David F. Machuca和麦吉尔大学的Roussos Dimitrakopoulos,本课程旨在展示最先进的统计和地质统计技术如何帮助以客观和可重复的方式回答关于矿产资源公开报告的最新法规要求。本课程特别强调通过矿产资源估算过程了解各种不确定性和误差的来源,以及如何通过应用矿产资源分类的定量和定性标准来表征地质。在工程模拟学科的大背景下,本课程全面介绍了矿产资源模拟的行业最佳实践。本课程适用于勘探和矿山地质学家、资源分析学家、采矿工程师以及相关领域的管理人员。 通过本课程学员可以学习到以下内容:(1) 如何构思和制作能满足矿业公司短期和长期需求的矿产资源模型
