Room and pillar mining - Wikipedia

Process Stage 1—exploration and development. Planning for the development of room and pillar mines operates in much the same way as other mining methods, and begins with establishing ownership of the mine. Following this, the geology of the mine must be analysed, as this will determine factors like the lifespan of the mine, the production requirements, and the cost to develop and maintain.
