It is a mining system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. To do this, "rooms" of ore are dug out while "pillars" of untouched material are left to support the roof – overburden.

1. INTRODUCCIÓN. En minería subterránea, los pilares son la roca in-situ que queda entre dos o más excavaciones (Martin y Maybee, 2000) y, por lo tanto, son el principal soporte utilizado para resistir colapsos y hundimientos.
The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds.
Bord and pillar mining method comprises two phases, i.e., development or ‘whole working' and depillaring or ‘broken working'. Sometimes both these phases proceed simultaneously.
Introduction: Room and Pillar mining method is one of the oldest existing methods in underground mining unsupported methods. In room-and-pillar mining, openings are driven orthogonally and at regular intervals in a mineral deposit – forming rectangular or square pillars for natural support.
