WiDesAI (kiWI Desi AI Bot) South Eastern Coalfields Limited (SECL) is poised to revolutionize coal mining in India by becoming the first Coal Public Sector Undertaking (PSU) to adopt paste fill technology. This groundbreaking initiative represents a significant leap towards sustainable and environmentally responsible mining practices.
A landmark Rs 7,040 crore agreement with TMC Mineral Resources Private Limited will see the implementation of this innovative technology at the Singhali underground coal mine in SECL’s Korba area. The project is projected to yield approximately 8.4 million tonnes of coal over a 25-year lifespan.
Paste fill technology offers a compelling solution to the environmental challenges associated with traditional underground mining. After coal extraction, the mined-out voids are filled with a specialized paste composed of fly ash, crushed overburden, cement, water, and binding agents. This process offers several key advantages:
- Enhanced Land Stability: The paste effectively prevents land subsidence, ensuring the structural integrity of the mine and surrounding areas.
- Environmental Sustainability: The utilization of industrial waste materials in the paste promotes waste recycling and minimizes environmental impact.
- Reduced Surface Disturbance: This method eliminates the need for extensive surface land acquisition, reducing the footprint of mining operations.
The Singhali mine, operational since 1993, presents a unique opportunity for this technological advancement. Previously employing the Bord and Pillar method, the mine’s location, with its densely populated surface area, presented significant challenges for traditional caving methods. Paste fill technology provides a safe and environmentally sound alternative.
SECL Managing Director Harish Duhan hailed the project as a landmark achievement, emphasizing its role in securing the future of underground mining while promoting eco-friendly solutions. This initiative sets a new benchmark for the Indian coal industry, showcasing a commitment to sustainable practices and paving the way for wider adoption of paste fill technology across the sector.Share
