Coal Mining MethodsThe Actual Difference Between Surface and Underground Mining

Other underground coal mines are laid out in a checkerboard of rooms and pillars Fig 2 and the mining operation involves cyclical step by step mining sequenc The rooms are the empty areas from which coal has been mined and the pillars are blocks of coal generally 40 to 80 feet on a side left to support the mine roofThere are two ways to extract a mineral by digging it up or accessing it by tunnels This pretty much sums up the comparison of surface vs underground mining But is it that simple For a better understanding ScienceStruck gives more differences between these two methods
