| 中文摘要: |
| 固体矿产勘查施工探矿工程的目的之一,首先是为获取矿体真厚度这一资源储量估算中的重要参数。但在其有关的固体矿产勘查规范、规程及矿产勘查教材中,所给出的矿层真厚度计算综合公式至今并不完善,在常规的条件下其计算结果时有出错问题的发生:一类为计算结果M≤0的明显错误,另一类为似是而非的计算结果错误；从而误导了矿产资源储量估算的结果。在最新的GB/T33444-2016《固体矿产勘查工作规范》中,这一问题依然存在。该文经分析论证找出了问题的根源,提出了改进后的砂体真厚度综合公式:M=L· (cosα· sinβ-sinα· cosβ· cosγ) ,用以满足固体矿产勘查工作中对矿体真厚度的正确计算。 |
| 英文摘要: |
| One of the purposes of solid mineral exploration engineering is to obtain the true thickness of orebody, which is an important parameter in resource reserve estimation. However, the composite calculating formula for the true thickness of the ore bed given in the specifaction and regulation for exploration of solid mineral resources and mineral exploration textbooks is not perfect until now. Under conventional conditions, errors occur in the calculation results:one is the obvious error of the calculation result M≤0, and the other is the specious calculation result. Thus they mislead the results of mineral reserves estimation. This problem still exists in the latest GB/T33444-2016 Specifieation for Exploration of Solid Mineral Resources. After analysis and demonstration, the root cause of the problem is found out, and the improved composite calculating formula is put forward:M=L·(cosα·sinβ-sinα·cosβ·cosγ),so as to satisfy the correct calculation of the orebody true thinkness in solid mineral exploration. |
