Abstract
Stability classification of roadway surrounding rock is of great significance as the prerequisite of safe production in roadway engineering. Based on a great number of issues analysis, the research status of roadway surrounding rock stability classification has been dissected from aspects of classification indexes and methods. At the end, it has put forward that choosing scientific and reasonable indexes, applying combined technology with more than three methods, using new technology and new methods are the three development trends of roadway surrounding rock stability classification research.
