SECL to become first Coal PSU to use paste fill technology for mining

South Eastern Coalfields Limited (SECL) is set to become the first coal PSU in India to adopt paste fill technology for coal mining—marking a major step toward sustainable and environmentally friendly mining practices. To implement this innovative underground mining technology, SECL has signed a ₹7040 crore agreement with TMC Mineral Resources Private Limited. Under this agreement, large-scale coal production will be undertaken using paste fill technology in the Singhali underground coal mine located in SECL’s Korba area. Over a period of 25 years, the project is expected to produce approximately 8.4 million tonnes (84.5 lakh tonnes) of coal.
