Room and Pillar Mining In this method, mining is carried out in an ore deposit, leaving behind some of the ore in the form of columns to support the roof and prevent it from collapsing. Thus, it results in the formation of spaces called ‘rooms’, where the ore is excavated with ‘pillars’ of ore distributed throughout.

Room and pillar mining - Wikipedia

Room and pillar (variant of breast stoping), 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.Calculating the size, shape, and position of pillars is a complicated procedure, and is an area of ...
