Reasonable Layout and Supporting for Floor Roadway Under Room and Pillar Mining Gob

More Information
  • Published Date: November 19, 2014
  • Taking a coal mine in Shanxi Province as background, using geotechnical engineering mechanical analysis calculation software FLAC3D, we had analyzed the stress field and the failure characteristics of the surrounding rock in room and pillar gob, and on this basis, we determined the reasonable layout for floor roadway. Then, we proposed the roadway support scheme and monitored the supporting effect. The results show that the floor roadway deformation is under control and the roadway support scheme is effective.
