    • Abstract
  • For the characteristics of long-term and large deformation of the deep soft rock roadway, we propose a technology to achieve pressure relief for full section of roadway base on "anchor cable in roof and two sides' roadway + pressure relief groove in roadway floor". It can ensure the support structure and provide high strength support resistance to the surrounding rock deformation and avoid premature failure. Taking support engineering at the track roadway of 28 mining area in Cheji Coal Mine as engineering, we use the technology of pressure relief for full section of roadway to control deformation of surrounding rock.
