Status of Mine Development

LCDC has 45 mines fully developed and capable of each producing average 20 M. tonnes coal per day while 12 mines are under development. Coal excavation is carried out by applying shortfall retreating method after developing coal panels at 50 ft interval. When a panel is completely mined, it is sealed off and coal excavation is started from next panel. Ventilation circuit is maintained through main incline as intake and main shaft as return air way. In case mine workings are extended far away from main shaft, an additional shaft is provided to improve airflow through coal face. Shaft is also used for coal hauling and material lowering while incline is also used as travelling way for labor.

The upto-date position of block wise-breakup of coal mines including additional shafts is as under:
