Influence of support stiffness on face stability in longwall face with large cutting height
Longwall mining with large cutting height serves as one of main methods for extracting thick coal seam. Face failure gradually becomes a critical phenomenon due to significant increase of the cutting height, which drastically influences the mining efficiency in such longwall faces. In order to impro...
