Abstract:By way of the indentification of total receiving sample principle, it obtains the inspecting criterion So of the masses of coal separation products and the sample capacity that should be taken out . The smallest capacity of the sample that should be take out when we estimate total square deviation when use the scheme.
Keywords:coal prepartion product  inspecting criterion  sample capacity  normal distribution  total square deviation
