Abstract:When preparing multiple coal samples in one sample preparation room, it is easy to cause samples mixing. In order to solve the problem, a multifunctional integrated sample preparation vehicle (unit) is developed. This vehicle could absorb, optimize and integrate the numerous fragmented elements at sample preparing spot, and make a centralized management of many issues in one sample preparing process, such as store，the label writing and pasting of prepared sample. And it makes the sample preparation order more clear and avoids the samples mixing to the maximum.
