| Bed separation | Mining | The thin cavities formed along bedding planes due to differential lowering of strata over mine workings; e.g., a shale with its greater bending capacity will subside and separate from a higher bed of sandstone. Roof supports are so set as to keep bed separation to a minimum. (references) | |
