    • Abstract
  • In order to study the leading factors affecting the stability of surrounding rock in gob-side entry at large height mining working face, taking 130205 gob-side entry in Yangchangwan Mine as an example, based on FLAC3D numerical simulation software, the influence laws of the coal pillar width, the height of the working face and mining strength on the stability of the surrounding rock are explored. Research shows that the influential intensity of the coal pillar width and mining strength are stronger than the height of the working face, and the stress and deformation distribution of surrounding rock is obvious asymmetry. The asymmetry is more obvious when the width of the coal pillar is smaller and the mining strength is stronger.
