摘要
针对进口集装箱装运精粉矿产品水分取样代表性问题,从精粉矿产品倒箱前后不同部位水分分布、取样铲取样不同份样数下样品代表性和三种常见取样工具取样代表性这三个方面进行研究,得出了进口集装箱装运精粉矿产品倒箱前后水分分布特点,以及采用取样铲取样时每箱不同份样数引起的水分差异,另外发现不同取样工具取样代表性差异。
Dealing with the problem of representativeness of sampling for imported concentrates minerals with container shipment,the moisture distribution of different parts before and after unloading the cargo and the representativeness of shovel sampling with different sampling numbers and three common sampling tools were studied.We obtain results about the moisture distribution of different parts before and after unloading and the moisture difference caused by sampling numbers sampled with shovel.Also the differences of representativeness of sampling between different sampling tools are found.
