UNDERGROUND TECHNOLOGYSECL is in its strive for higher production from underground mines has successfully introduced thick seam extraction with cable bolting, depillaring of contiguous seams with floor pinning and Powered Support Longwall Technology with Chinese Collaboration at Balrampur and Rajendra Under Ground Mines, Mass production technology with continuous miners in collaboration with UK and other developed countries, Hydro-fracturing and long hole blasting at goaf from underground for hard roof management at Churcha West Mines, Indigenously developed Cutter Loader to avoid blasting in gassy mine etc.
MASS PRODUCTION TECHNOLOGY
OPENCAST TECHNOLOGYUp-gradation of technology is a continuous process. Modern generation shovels and dumpers having capacity 10 meter cube and 120 Te dumper are being used in Open Cast mines. With use of such HEMMs, SECL has the distinction of operating biggest opencast mine in the country. As a Major mechanization drive in opencast mining, 42 Cum Electric Rope Shovels and 240 Te. Dumpers have been deployed for the first time in the country at Gevra & Dipka Mega OC projects.
