The Room and Pillar Method, also referred to as the Pillar and Stall Method, is one of the world's oldest mining systems. Dating beyond the 1840s, this method has been commonly used in mining coal, iron, and other base metals. In the 1970s, over 50% of coal mining in the United States used this method. Today, it remains the most popular coal,

26/04/2021· The room and pillar mining method has been considered as an effective mining strategy for gently inclined medium-thick orebodies [5–7]. However, this method greatly disturbs the initial stress within the rock. Due to mining activity, the overlying rock mass of the stope undergoes continuous dynamic changes in its stress and displacement fields under

This method, called “room and pillar” mining, usually requires that pillars of salt be left at regular intervals to prevent the mine from collapsing (Figure 5.4). Another method, called solution mining, involves drilling a well into a layer of salt. In some cases, the salt exists as part of a brine that can then be pumped to the surface and the water then removed, leaving the salt behind,
