    • Abstract
  • Aiming at the characters of pressure behavior strongly in belt conveyor downhill sections (240 m), the article presents the solution of "high-strength cable + bottom + concrete arch grille combined support" program to meet the geological conditions. The results show that roadway deformation is large and mine pressure behavior is strong after merely adopting "bolt + cable" to support roadway, the stabilityof soft rock roadway surrounding is controlled effectively with good technical and economic benefits after adopting a joint support scheme.
