room and pillar mining overviewplanning 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.
next, mine layout should be determined, as factors like ventilation, electrical power, and haulage of the
