Abstract：A discussion on zonal disintegration phenomenon and related theoretical problems in surrounding rocks of deep roadways were held in an academic salon about new ideas and new theories by Chinese Society for Rock Mechanics and Engineering. The contents of this academic salon cover the latest research achievements on zonal disintegration，e.g. measurement in-situ stresses and experimental research result analyses of a laboratory，explanation and different phenomena and their formation mechanisms about zonal disintegration，and the development of numerical analysis methods. Moreover，some hot issues such as the meaning and research methods about zonal disintegration are also discussed. Although the study of zonal disintegration is in a groping state and some controversies on present research results still exist，the discussions are very helpful for scientific achievement in this research subject and have an enlightening influence on acknowledgement and disposal methods of this research work on zonal disintegration.
