·Most open cast mines require the removal of overburden and waste material to access the underlying orebody This activity is known as stripping By their nature all open pits become narrower with depth and consequently the volume of waste to be stripped is largest on the upper benches that must be mined first The problem is mitigated
·Mountaintop removal This method involves blasting away the top of a mountain to access the coal seams inside generating large quantities of overburden Quarrying Quarrying operations for extracting building stone aggregate sand and gravel also produce overburden though the volume may vary based on the size and depth of the quarry
The removal of this overburden is known as Over burden Removal OBR and involves heavy cost OBR is an important performance parameter as it exposes the coal seam for future production at short notice Stripping activity It is the activity of overburden removal that benefits the identified component of an ore to be mined by the entity
