Room and Pillar is a mining method used primarily for extracting coal and other minerals. In this technique, large blocks of material are left intact, creating "rooms" where the resource is mined, while "pillars" of material are left standing to support the mine's roof. This method helps to maintain stability and safety in underground operations. The design of Room and Pillar mining allows for efficient extraction while minimizing the risk of collapse. It is commonly used in flat-lying deposits and can be adapted to various geological conditions. This method is also known for its relatively low environmental impact compared to other mining techniques.
