Coal India Ltd. (CIL) and its subsidiaries coal companies are taking corrective measures for improving quality of Coal.

The subsidiary coal companies of CIL supply coal to all thermal power plants in accordance with the provisions of Fuel Supply Agreement (FSA). In terms of FSA, third party sampling and analysis facilities at loading ends are provided to the power utilities for assessment of quality of coal at loading end jointly and thereby loading of proper quality coal to power companies is ensured.

As per the provisions of FSA, the consumers are to make payment of coal bills in accordance with the quality of coal so determined at loading end for sampling and analysis by the third party in presence of the representatives of the consumer. Additionally, power plants are compensated for the Stone or Boulders of 250 mm size segregated at the unloading end, after joint assessment.

    Selective mining of bands of thickness more than 1 meter.
    Appropriate positioning of overburden and coal benches to avoid contamination.
    Scrapping or cleaning of coal benches before blasting.
    Installation of metal detectors or magnetic separators over running conveyors before coal loading.
    Crushing arrangement for supply of sized coal for better consumers satisfaction.
    All the major projects having high capacity coal handling plants dispatch sized and uniform quality of coal to suit the requirement of the consumers.
    Bomb Calorimeters provided at all the area laboratories at all the major projects for regular quality assessment.
