    • Abstract
  • The pumping stations in Peigou 42 mining area,with poor surrounding rock,long years of service,deep buried and big stress,is influenced by fault and has big residual tectonic stress.The paper analyzed the U-shaped steel roof support and the severe deformation reason after the roadway dug up shortly.Through the surrounding rock grouting,and the shelf cable collaborative support in roof and sides parts to increase the structural stability,its carrying capacity was enhanced,and heaving floor was controlled by anchors and cables support in floor.Field measurements after the implementation of the program showed that the program had effectively controlled the surrounding rock deformation.
