Sampling Standards. All sampling standards, whether ISO, ASTM International, or an individual nation's standard, recognize that the best time to collect the a sample is when the material (in this case coal) is being moved from one location to another via conveyor belt.

Coal sample, irrespective of grain size, is packed into an oxygen-free polyethylene "rabbit" of about 2.5 mliter capacity (see Fig. 7), or larger, pressing to compactness if it is a fine powder.The container is closed, weighed, and sealed with a hot rotating platinum rod, and the seam is examined with a binocular microscope for possible holes.
Standard Laboratories, Inc. has the facilities to provide a wide variety of coal sampling and testing, as well as other support services for the coal mining and processing industries. We have facilities and partner companies throughout the United States to assist projects in any region of the country.
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

Sample Preparation: The coal sample collected is prepared and reduced to an appropriate size at preparation room of coal company. The sample collected is reduced to a size of 12.5 mm for determination of total moisture content. The prepared sample is further reduced to a .
The normal preparation procedure requires that each air-dried coal sample pass through a jaw crusher; one subsample (split) of the crushed material (2 to 4 mm, or 5 to 10 mesh) is then taken for the ultimate and proximate analyses, and another split is reduced to approximately 150 m m (100 mesh) by a vertical grinder for chemical analysis.

The method used to reduce the gross sample to the analytical sample must maintain the integrity and repre- sentativeness of the sample while meet- ing the particle size and weight require- ments as specified by the particular analytical methods. The preparation of a gross sample for coal analysis requires several process- ing steps.
sampling assignments may be undertaken independently, In this case there may be possibility of variation in results for inherent nature of coal. B. Preparation and analysis of coal samples. i. Modalities for storage and preparation of joint samples would be strictly as per guidelines given by Coal Controller office/Bureau of Indian
coal samples, such as brown coal, the sample preparation step becomes even more important in ensuring reproducible analysis results. The fineness of the sample can influence the standard deviation of the analysis results, as will be shown in this article using brown coal as an example. In general, using a sample divider to
