Effect of mining parameters on surface deformation and coal pillar stability under customized shortwall mining of deep extra-thick coal seams
Underestimation of customized shortwall mining parameters of deep extra-thick coal seams (namely, mining height, mining width, and pillar width) may result in coal pillar instability, surface subsidence, and mining structure failure, while their overestimation would cause a waste of coal resources....
