    • Abstract
  • According to the mining geological conditions of soft rock roadway influenced by overhead mining in Fengfeng Mining Area, using numerical simulation software FLAC2D, we research the activity laws of surrounding rock. The result shows that the displacement and stress of surrounding rock strongly influenced by the mining face stress and displacement field are unsymmetrical in the process of overhead mining, and the displacement of surrounding rock and stress reduction are synchronized. According to the laws of the surrounding rock activity for such roadway, taking the reinforcement technology of U-steel support and backfilling in weak parts can make support-surrounding rock structure bear together.
