Coal sampling, whether per- formed manually or automatically, must extract a quantity of coal much smaller than the original lot for labora- tory analysis. The sample, to be repre- sentative, must have the same charac- teristic qualities and constituents as the entire coal lot. However, inherent vari- ability in the coal parameters and the ...
