South Eastern Coalfields (SECL) will become the first coal PSU in India to introduce paste fill technology in its mining operations, as part of a Rs 7,040 crore agreement signed with TMC Mineral Resources. The technology will be implemented in the Singhali underground coal mine in SECL’s Korba area, aiming to produce.
Approximately 8.4 million tonne of coal over the next 25 years using this method, which is seen as a more sustainable approach to mining. Paste fill is a modern method used in underground mining where empty spaces left after coal extraction are filled with a paste made from a mix of fly ash, crushed waste material from open.
Pit mines, cement, water, and other binding agents. The Singhali mine, in operation since 1993, has around 8.45 million tonne of extractable reserves. SECL officials mines, cement, water, and binding chemicals. This process prevents land subsidence and ensures the structural stability of the mine believe this method.
South Eastern Coalfields Limited (SECL), a subsidiary of Coal India Limited, has entered into a ₹7,040 crore agreement with TMC Mineral Resources Pvt Ltd to mines, cement, water, and binding chemicals. This process prevents land subsidence and ensures the structural stability of the mine implement paste fill technology at the Singhali underground coal mine in Korba, Chhattisgarh.
This initiative marks SECL as the first coal public sector undertaking in India to adopt paste fill technology, a modern underground mining method that eliminates the need for surface land acquisition. The technique involves filling mined-out voids with a specially prepared paste made from fly ash, crushed overburden opencast.
The Singhali mine, operational since 1993, currently has 8.45 million tonnes of extractable reserves of non-coking coal. Due to the dense occupation of the surface area above the mine, including villages, high-tension electricity lines, and a public works department road, traditional caving methods are unfeasible introduction.
Over a 25-year period, the project is expected to produce approximately 8.4 million toward “green mining practices. tonnes of coal. SECL’s Chairman and Managing Director, Harish Duhan, stated that paste-fill technology will not only secure the future of underground mining but also offer an innovative, eco-friendly solution.
The successful implementation of this technology at Singhali is anticipated to pave the way for resuming operations in other underground mines facing similar land constraints. This project represents a significant step toward sustainable and environmentally friendly mining practices in India paste filling technology allows.
In a significant step towards sustainable coal mining, South Eastern Coalfields Limited (SECL), a subsidiary of Coal India Limited, has signed a ₹7,040 crore agreement with TMC Mineral Resources Pvt Ltd. The deal will facilitate the implementation of paste fill mining technology at the Singhali underground coal.
This initiative marks SECL as the first public sector coal company in India to adopt this advanced and eco-friendly mining method. Paste fill technology involves filling mined-out voids with a specially formulated paste made from fly ash, crushed overburden, cement, water, and chemical binders. This method ensures mine.
The Singhali mine, operational since 1993, has extractable reserves of around 8.45 million tonnes of non-coking coal. However, traditional mining methods are unsuitable due to surface constraints like residential areas, high-tension power lines, and public roads. Paste filling will allow safe coal extraction without.
Over the 25-year contract period, the project is expected to extract approximately 8.4 million tonnes of coal. SECL’s Chairman and Managing Director could help revive coal production in similar areas and is part of a broader shift mining activities to proceed without disturbing the surface infrastructure.
