    Definition and formation: Sandstone is a common roof rock above many coal beds. It is especially common beneath paleochannel deposits, and transitional with some stackrock deposits. Thick-sandstone mine roofs commonly offer good roof conditions. Sandstone tops may have local weaknesses along bedding, however, which can lead to roof falls.
