在普查和勘探工作中,采样与化验工作是研究矿石物质成分及其质量变化的重要手段.通过矿样的化验,了解矿石中的主要有益组份的含量及其他有益有害组份的含量,藉以确定矿石的品位及其与围岩的界线和掌握矿体组份间的互相变化情况.因此采样长度选择得适当与否,将会直接影响到对矿区的正确评价,而且也能替国家节省或浪费大量资金.以往对各种矿床的采样长度,都有一般的规定,如铁矿之采样长度,一般不应大于三公尺,铝土矿一般
In the census and exploration work, sampling and testing work is an important means to study the composition and quality of ore, and through the test of ore samples, we can understand the content of the main benefit components and the content of other beneficial harmful components in ore Determining the grade of ore and its boundary with the surrounding rock and mastering the mutual change between the ore body components, the proper sampling length will directly affect the correct evaluation of the mining area, but also for the country to save or Waste a lot of money in the past for a variety of deposit length of sampling, there are general provisions, such as the length of the sampling iron ore, generally not more than three meters, bauxite general
