NTPC completes trial operation of fly ash disposal system

NTPC Limited has completed the trial operation of the fly ash disposal system at Northern Coalfields Limited’s (NCL) Gorbi mine void (Pit-1).

Fly ash from the bulker was transported by pressurised air to a hydro mix chamber and converted to slurry for dumping in the pit. In January 2019, NTPC Vindhyachal and NCL signed an MoU and after carrying out various kinds of environmental studies and obtaining clearances from statutory authorities, the required ash disposal equipment was installed and the trial could be accomplished. It will open up a major opportunity to develop the abandoned mine in an environment-friendly manner for utilisation of ash. This mine pit was abandoned in 1996-97.
