How a Continuous Miner Works in 2023 | Underground Mining
Before implementing a continuous mining system, mining companies must divide each mine into 20 to 30 coal beds. Then, workers must install support systems to prevent the mine from collapsing. After carving work areas into the coal beds, mining teams can begin setting up continuous miners to extract coal.
