Abstract :

The subsidence around the Baropukuria Coal Mine field is the most important and major hazards or threats for safely extracting the coal from underground. From this point of view, the present research mainly investigated the causes of subsidence and its possible preventive plans by direct field investigation method. The analysis shows that subsidence is caused by many factors such as applied mining method, multi-sliced ultra thick coal seams, less competency of overburden strata, depth & dip of the coal seam, existed geologic discontinuities such as faults, Joints, fissures and other inconsistencies in the overlying and surrounding strata around the mine. Investigation also implied that the subsidence cannot be eliminated thoroughly but can be reduced with completely changing the applied on going mining methods or redesigning the mining plan in the area.
