Coal sampling and preparation. Coal sampling is performed whenever there is a need to analyse the coal. Coal is highly heterogeneous in nature consisting of particles of various shapes and sizes each having different physical characteristics, chemical properties and residual ash content. Sampling is further complicated by the sampling equipment ...

The fundamental sampling process has three main steps. Firstly, getting a coal sample from the entire coal lot, we call these coal briquettes as a primary increment. Then combining all primary increments which are divided and the nondivided primary increments together, which calls the gross sample.

Coal sampling may be defined as the extraction of a small amount of material from a larger bulk of coal such that the sample extracted is representative, as far as possible, for all analytes of interest. Sample preparation, which may involve drying, crushing, and subsampling, is an integral part of the sampling process.

After coal mining this process, the next step is coal sampling. Coal sampling . Coal sampling is an essential step for purchasing bulk coal. Why do we say that? Coal sampling aims to provide a representative sample for sample test to inspect the characters of bulk coal. The representative sample ensures the accurate characters of coal.

Condition D (Stationary Coal Sampling), in which a portion of coal is collected from a pile, a rail car, a barge, or a shiphold. Spacing of Increments—The spacing of increments pertains to the kind of intervals between increments. Two spacing methods are recognized: systematic and random. Systematic spacing is usually preferable.
