Room and Pillar Mining Method Overview by ScribdTranslations is a document available to read on EtoBox.
The room and pillar method is the only practical one for mining horizontal layers of low power such as stratified deposits of sedimentary origin.

There are variants such as inclined room and pillar for inclined deposits where the mined space is backfilled to stabilize the pillars.
