本文包括绪言、地质环境、勘探,开采品位和品位控制,矿石储量计算、结果及结论等七个部分。 绪言中阐明矿石储量报告是对特定体积内金属含量的估算。它的质量不仅取决于采样的密度,而且也取决于所用的估算方法是否合适。矿石储量报告是对矿体进行经济评价所需要的一项最重要的数据。每一种估算都会直接影响到投资的规模,以及矿山生产过程中的财政稳定性。 地质环境和勘探中论述了位于金岛的多尔芬矿体是一个产于层状钙硅酸盐岩石中热液交代成因的矿床,采用金刚石钻探,钻孔从地表钻进至-7～-280米标高之间切穿矿体的部位为止。钻孔剖面间距的选择是在衡量了钻探费用与矿石资源后估算精度之
This article includes the introduction, geological environment, exploration, mining grade and grade control, ore reserves calculation, results and conclusions of seven parts. The introduction states that the Ore Reserves Report is an estimate of the metal content in a given volume. Its quality depends not only on the density of the sample, but also on the suitability of the estimation method used. The Ore Reserves Report is one of the most important data needed for the economic evaluation of ore bodies. Each estimate directly affects the size of the investment and the financial stability of the mine during its production. Geological environment and prospecting discussed that the Dolphin ore body located in the island of Gold Island is a genesis of genesis of hydrothermal metasomatism in layered calc-silicate rocks. Diamond drilling is used to drill through the surface to reach a depth of -7 ~ 280 meters elevation cut between the parts of ore body so far. The choice of borehole profile spacing is a measure of the accuracy of drilling costs and ore resources
