South Eastern Coalfields Ltd (SECL), a subsidiary of Coal India, has entered into a Rs 7.0 bn agreement with TMC Mineral Resources for large-scale coal production using innovative paste filling technology. This pioneering move positions SECL as the first coal public sector unit (PSU) in India to adopt this advanced underground mining method. Paste Filling Technology: A Sustainable Mining Solution Paste filling technology involves filling the mined-out voids in underground mines with a specially formulated paste. The paste is made from fly ash, crushed overburden from open-cast mines, cement, water, and binding chemicals. This method eliminates the need for surface land acquisition, preventing land subsidence, and ensuring the structural stability of the mine. The technology enhances the sustainability of coal mining by mitigating environmental impacts and ensuring safe, efficient operations. SECL’s adoption of this technology marks a significant step towards innovation in the mining sector. A Groundbreaking Partnership This agreement with TMC Mineral Resources will be instrumental in implementing paste filling technology at the Singhali underground coal mine in SECL’s Korba area. The deal is expected to revolutionise the mining process, bringing about significant advancements in both production and environmental management.
