19 coal mines allocated for sustainable fly ash disposal

In a strategic move towards environmental sustainability, the Ministry of Coal (MoC) has allocated 19 coal mine voids to 13 thermal power plants (TPPs) for the disposal of fly ash. This initiative aims to mitigate the environmental impact of coal combustion and promote the reuse of fly ash in various applications.

A Central Level Working Group (CLWG), chaired by the Additional Secretary of the Ministry of Coal, was established in 2023 to oversee this process. Thermal power plants interested in utilising mine voids for fly ash disposal submit their applications to the Central Electricity Authority (CEA), which are then reviewed in CLWG meetings. This systematic allocation addresses environmental concerns associated with fly ash while promoting sustainable practices within the coal mining sector.

To date, approximately 20.39 lakh tonnes of fly ash have been successfully repurposed at the Gorbicoal mine pit-1, demonstrating the practical benefits of this initiative. The Ministry of Environment, Forest and Climate Change, in its notification dated 3 November 2009, defines "fly ash" to include various forms such as Electrostatic Precipitator (ESP) ash, dry fly ash, bottom ash, pond ash, and mound ash. Rich in silicon dioxide (SiO2), calcium oxide (CaO), and aluminium oxide (Al2O3), fly ash is increasingly valued for its potential in construction and other industrial applications.

The Ministry of Coal, in collaboration with the Central Mine Planning and Design Institute (CMPDI), is also developing a centralised portal to streamline the application process for the allocation of mine voids. This portal is expected to enhance transparency and efficiency in managing fly ash backfilling activities.

Furthering its commitment to sustainable mining practices, the Ministry is conducting comprehensive feasibility studies to determine the optimal methods for mixing fly ash with overburden in operational mines. These studies, conducted in collaboration with the Central Institute of Mining and Fuel Research (CIMFR), include significant research at the Nigahi operational mine to establish the best percentage of fly ash to be mixed with overburden. Results from these studies are anticipated soon.

Through these initiatives, the Ministry of Coal is ensuring the safe handling and management of fly ash, mitigating potential environmental risks associated with heavy metal leaching and fine particle emissions. By fostering collaboration with power plants, industries, and regulatory bodies, the Ministry aims to achieve optimal fly ash management, paving the way for a cleaner environment and a more sustainable approach to energy generation in India.
