在国外,铜矿资源大多是露天开采的.例如,美国露天开采的铜矿占总产量的89%.而且,斑岩铜矿几乎全是露天开采的.我国解放以来,各种类型的矿种露天开采的矿山也在不断增多.露天矿不仅矿石的采出率高,贫化率低,生产安全,采矿成本低,而且可以采用现代化设备扩大生产规模,能提供数量多、质量好的矿物原料.露采矿山和坑采矿山的勘探和研究虽有共同的地方(例如,矿石的物质成分和可选性能方面的研究),但是,在矿床的控制程度和高级储量的分布方面,则有所不同.因此,对于露天开采的矿床如何进行勘探的问
For example, open-pit copper mines account for 89% of the total output in the United States, and almost all of the porphyry copper mines are open-pit mined.After the liberation of China, various types of minerals Open-pit mines are also growing.Open mines not only high ore recovery rate, low depletion rate, production safety, mining costs low, and can use modern equipment to expand production scale, can provide a large number, good quality mineral raw materials Although exploration and research in opencast and pit mines share common ground (for example, studies on the composition of matter and optional properties of ores), there is evidence of the degree of mineralization and the distribution of advanced reserves Different.Therefore, how to conduct exploration of open-pit deposits
