A rock burst roadway safety monitoring method, comprising: comparing the monitored vibration speed, strain and stress of a roadway surrounding rock during a rock burst occurrence process with a critical value of instability of the roadway surrounding rock, so as to determine the stability of the roadway surrounding rock (100); comparing the monitored stress and deformation of a first supporting structure, which is located on the surface layer of a roadway, during the rock burst occurrence process with a critical value of instability of the first supporting structure, so as to determine the stability of the first supporting structure (101); comparing the monitored stress and deformation of a second supporting structure, which is located in the inner space of the roadway, during the rock burst occurrence process with a critical value of instability of the second supporting structure, so as to determine the stability of the second supporting structure (102); and determining a roadway safety level according to th
