CONTROLLED CAVING

Domain	Definition
Mining	A mining method utilizing the advantages of longwalls, but at the same time without filling. In this method, the working room in front of the working face is protected by close lines of props and cribs, which are portable and easily taken to pieces. As the face proceeds, the cribs are shifted as well as the props with the face, leaving the mined-out room tocave. This method is also called mining with self-filling. (references)
