Room and pillar mining is a mining method used for extracting minerals, typically coal or ore deposits. It involves creating a grid of rooms and leaving pillars of untouched material to support the roof. Miners extract the resource from the rooms, leaving the pillars to provide structural integrity. This method is often used in underground mining to maximize resource recovery while maintaining safety and stability. Follow us at tunnel.engineering Video courtesy of Epiroc #mining #miningengineeri

MINADO POR CÁMARAS Y PILARES ("ROOM AND PILLAR"). Este método consiste en la explotación de caserones separados por pilares de sostenimiento del techo. La recuperación de los pilares puede ser parcial o total, en este último caso, la recuperación va acompañada del hundimiento controlado del techo que puede realizarse junto con la explotación o al final de la vida del yacimiento, lógicamente el hundimiento del techo en este caso es totalmente controlado.
