Quality Aspects

Quality Aspects


Consumer satisfaction is the prime objective and motto of MCL. Coal is natural products and heterogeneous in nature. It is mines from earth crust and not manufactured product. Hence the procedure and method of Quality Control are different from other manufacturing industries. Following measures are taken for quality improvement.

Proper Assessment and Rationalized Grading of In-Situ Coal Quality


By adopting stringent sampling procedure in case of seam, stock, siding and tipper samples, the annual coal grade is being declared every year for the utmost satisfaction of the consumers.

Proper Sizing

Before dispatch the coal from mine end / stock is being transported to Feeder Breaker / CHP for crushing of coal up to size (-) 100 mm and then this (-) 100 mm sized coal is being transported to all Railway Sidings.

Apart from this MCL is having sufficient Surface Miner in all the Projects from which proper sizing of coal is being produced and dispatched directly to the Sidings for final dispatch to the consumer. In addition to this, the intermittent band in the coal seams is being separated and thrown out as reject to maintain the quality of coal.


Proper Weighment of Coal before Despatchstrong>

Before dispatch of coal by rail all the rakes are being weighed at In-motion Rail Weighbridges.

Electronic Rail Weighbridges with print out facility exist at all Railway Sidings. Apart from this, we have been provided with standby weighbridges for achieving the target of 100% weighment.

Coal being dispatched by road is having 100% weighment.

Proper Sampling and Analysis

Before dispatch of coal by rail proper sampling and analysis is being done at all Railway Sidings as per BIS method.

MCL is following strictly the guidelines of existing FSA on sampling and analysis of coal being dispatched to all consumers including power houses.

3rd Party sampling / analysis of coal is being done in response of representatives of the consumers.


Infrastructure for Analysis of Coal Samples

At present MCL is having a total of TEN (10) nos. of Coal Analysis Laboratories in different Areas which are well equipped with modern, sophisticated equipment like Auto proximate Analyzer and Auto Bomb Calorimeter for the determination of UHF and GCV of coal. By the help of such equipment GCV of coal can be determined within a period of 15-20 minutes.
