Room and Pillar Mining is a method used to extract minerals from underground deposits. In this technique, large blocks of ore are removed while leaving behind pillars of untouched material to support the mine's roof. This approach helps prevent collapses and allows for safer mining operations. The layout of the mine consists of rooms, where the ore is extracted, and pillars, which are the remaining sections that provide structural support. This method is commonly used for mining coal, gypsum, and salt, making it an essential technique in the mining industry.
