Thick coal seams are crucial for efficient coal mining, and different methods like large-cutting-height and top-coal caving are used. Ground control for these thick seams poses unique challenges due to the height of the cut, making it hard to support the roof directly above. When the upper roof collapses, it can put pressure on the mining shield and cause instability. To manage this, understanding the dynamic loads, ensuring coal face stability, and mastering top-coal extraction are vital for safe mining in thick coal seams.
