在如何确定矿山边界品位的问题上,过去我们的做法是,通过经济比较确定一个可采的边界品位,然后按此边界品位进行储量计算。结果就只有一种边界品位的矿石储量。而外国公司在矿山设计方法与程序上有很多地方与我们过去所使用的方法不同。例如美国福陆采矿金属公司在计算德兴铜矿的地质储量时,是采 On how to determine the quality of the mine boundary, in the past, our approach was to determine a recoverable boundary grade by economic comparison and then calculate the reserves according to the boundary grade. As a result, there is only one grade of ore reserves at the border. And foreign companies have many different ways and methods of mine design methods and procedures than we used to. For example, the United States Fluor Mining Corporation in calculating the geological reserves of Dexing Copper Mine, it is mining
