SAMPLING, SAMPLE PREPARATION AND ANALYTICAL PRACTICES 85 Introduction Coal consists of particles of varied shapes and sizes each having different physical characteristics, chemical properties and residual ash content. A correct and representative sample requires that every particle in a lot being sampled is equally represented1. Coal sampling
This practice covers laboratory procedures for the preparation of granular samples of bituminous coal and anthracite samples for examination with a microscope using reflected light illumination. It does not apply to the preparation of oriented blocks of coal. Units The values stated in either SI units or nonSI units are to be regarded separately as standard.
Coal samples may be required as part of a greeneld exploration programme to determine whether the coal is suitable for further investigation, or as part of a mine development programme, or as routine samples in opencast and underground mines to ensure that the quality of the coal to be mined will provide the specied run of mine product.

What Is Coal Preparation? Coal preparation is the removal of undesirable material from the RunofMine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation

OPEN CAST MINE PLANNING Factors that influence planning: 1) Demand of coal. a. Countrywide demand b. Regional demand 2) Distribution of coal deposits 3) Quality of coal 4) Pricing policy for coal 5) Available infrastructures: rail, road, power, etc. 6) Nature of deposits (influences site, area method of work, amp; equipments of mining)
The coal vibrating screen sets electronic counts and supports auto power onoff. It has an automatic controlling system and can unload material automatically. Coal Sample Division. Coal sample division is the most critical procedure in sample preparation. It aims to decrease the mass of the sample without changing the size.

The sample preparation method used in this study for metal determination in coal by spectroanalytical technique is dry ashing, and wet acid microwave digestion. A method is developed of the sample pretreatment and preparation procedures for metal determination in CBA here. MWAD followed by inductively coupled plasmaoptical
This procedure may be used to provide a sample of any mass and size consist from the gross or divided sample to, and including, the analysis sample. This practice also to give a sample preparation and analysis variance which is no more than 20 % of the total D3174 Test Method for Ash in the Analysis Sample of Coal and Coke from
