Room and Pillar Mining is a method used to extract minerals from underground deposits. In this technique, large rooms are created by removing the mineral, while pillars of untouched material are left to support the mine's roof. This design helps prevent collapses and allows for safer mining operations. The process typically involves drilling, blasting, and transporting the extracted material to the surface. Coal, potash, and salt are common minerals mined using this method. Room and pillar mining is often favored for its efficiency and lower environmental impact compared to other mining techniques.
