Design and Application of Rapid Digging Process Technology in Mine Mining
For the existing rapid tunneling operation scheme in Dongqu Coal Mine,and the problems in the support,the rapid tunneling support process improvement design,through the analysis and calculation of the anchor cable dry support parameters,optimize the tunneling process of the tunneling unit,the development of rapid tunneling and support process,and engineering applications,application results show that the program can effectively control the deformation of the surface of the roadway and the deep part of the surrounding rock,the anchor cable support can also meet the construction requirements.construction requirements.
