    • Abstract
  • Aiming at the support problems of soft rock roadway, the effect factors and control theory of surrounding rock stability in soft rock roadway are analyzed comprehensively. The comprehensive classification table and the support parameters table of surrounding rock in soft rock roadways are set up. Based on the comprehensive classification table of surrounding rock, deformation characteristics and rock plastic zone distribution of surrounding rock with different support design and parameters are deeply revealed by using FLAC3D simulation. The optimized support technologies are proposed for each class of surrounding rock. The support design and techniques of repairing and strengthening for haulage roadways are proposed according to the table. The field monitoring result shows that it can control the deformation of roadway effectively. The table will find promising engineering application in the support design and construction.
