Numerical Study on Soft Coal Pillar Stability in an Island Longwall Panel
Roadway support and management of longwall panels in an island soft coal panel are always difficult work. In a test mine, stress distribution, deformation characteristic, and plastic zone distribution around the roadway and coal pillars in the development and mining periods were investigated with re...
