Numerical Study on Soft Coal Pillar Stability in an Island Longwall Panel by Qingyun Xu, Jian-Biao Bai, Shuai Yan, Rui Wang, Shaoxu Wu

“…Finally, a reasonable width for coal pillars in an island panel was determined to be 5.0 m. Industrial practice indicated that a coal pillar width of 5.0 m efficiently controlled deformation of the surrounding rock, which was an important basis for choosing the width of coal pillars around gob-side entries in island longwall panels with similar geological conditions.…”
