Room and pillar miningWikipedia

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

Mining Facts for Kids

Surface mining is done by removing (stripping) surface vegetation dirt and if necessary layers of bedrock in order to reach buried ore deposits. Techniques of surface mining include open-pit mining which is the recovery of materials from an open pit in the ground quarrying identical to open-pit mining except that it refers to sand stone and clay strip mining which consists of

Typical face areas are 12.2 m wide x 7.6 m high (40 ft wide by 25 ft high) with 4.3 m (14 ft) pulled with each blast (Figure 1). This equates to over 1 000 tons of stone per
