Background
The coal sampling is a process of taking a representative coal sample according to a specified method. That is, a small portion of a sample representing the raw coal in terms of composition and properties is taken from the conveyor belt in a prescribed, scientific manner. However, the coal material is a very uneven solid material, and the unevenness is mainly determined by the changes of indexes such as moisture, ash content, volatile matter, granularity and the like in the coal material. The greater the ash content and particle size, the greater the coal material non-uniformity and the more difficult it is to collect a representative sample of coal. Because of the difference between the particle size and the density of the coal material, the natural separation and stratification of the large and small particles under the action of gravity is called segregation, which is also one of the causes of coal non-uniformity.
For sampling of heterogeneous coal, a representative sample must be obtained according to a scientific and satisfactory method, and the result of the analysis test is used to infer and evaluate the quality characteristics of the whole batch of coal. Therefore, sampling is the basis and the key in three links of coal sampling, sample preparation and assay.
