合理勘查工程间距导致资源储量估算偏差的原因分析
|
摘要
勘查工程间距是影响资源储量估算结果可靠性的最根本因素。国内现行勘查规范主要依据矿床勘查类型而确定基本勘查工程间距,该工程间距作为勘查工程部署和资源储量估算与分类的基本原则被广泛使用。但在实际工作中发现,依照规范推荐的勘查工程间距常常出现资源储量估算结果被明显夸大的情况。究其原因,既与勘查工作经济合理的商业规则有关,也与对勘查规范的理解存在偏差、勘查阶段取得数据的局限性以及对矿床地质特征和规律认识不充分有关。更深层次的看,国内现行规范与JORC等国外资源储量报告准则相比,仍未摆脱计划经济的桎梏,同勘查市场接轨、与矿床地质实际结合以及新技术新方法的运用方面还有很大的差距和进一步改进优化的空间。
Exploration engineering spacing is the most fundamental factors affecting the results reliability of mineral resources estimation.Existing domestic exploration standard determines the basic exploration engineering spacing mainly based on the exploration types of mineral deposit.It was widely used as the basic principles of mineral exploration,mineral resources estimation and classification.However,the mineral resources estimates are often obviously exaggerated in accordance with the specifications recommended exploration engineering spacing.The reasons for this may be caused by the economical and exploration business rules,the deviations of the understanding of mineral exploration standards,the data limitations obtained during mineral exploration and the un-sufficiently realizing of geological law of the mineral deposits.Moreover,the domestic mineral exploration standards are constrained by the planned economic regime comparing with the JORC reporting guidelines and have a great optimization potential in future.
