TABLE 6. VALUES OF VERTICAL STRESS FOR STAGE II AND III EXCAVATION. At present in Barapukuria Coal Mine, seam VI has been excavated in two stages, stage I with Longwall method, where, 3m of coal is kept as top coal of 2.8m's excavation. In stage II, 3 m coal is exca-vated with LTCC method with 3 m top coal.

The production of coal from 11 long-wall faces of 1st slice and the first face-1204 of the 2nd slice have already been completed. Recently, coal production is going on from the second face-1203 of 2nd slice. Long-wall top coal caving mining method will be applied for coal production and face-1210 will be developed in BCM.
