CIL to deploy more LHD/SDL to hike UG output

August 13: In order to augment its sagging coal production from underground (UG) mines, Coal India Ltd (CIL) plans to focus on semi-mechanised Bord and Pillar mining with load haul dumper (LHD) /side discharge loader (SDL) loading with continuous coal evacuation system.

“Universal drilling machines (UDMs) are also being deployed to increase productivity of SDL/LHD mines….Mass production technology methods with Continuous Miner (CM) and Powered Support Longwall (PSLW) faces, are now being planned to be introduced in phases in some of the underground mines,” CIL said in its annual report for the year 2013-14.

Also, a man-riding system is being installed in the underground mines to fully utilise the shift hours. This is expected to increased productivity and reduce the arduous travelling time of the personnel in the underground mines, it added.
