Abstract: Based on field exploration data and laboratory test data, comprehensively considered construction property and other factors of slope engineering, quality classification and evaluation were done on engineering rock mass of mine slope by adopted RMR and BQ methods, strength range of each rock mass of mining area were confirmed comprehensively. The example analysis indicates comprehensive forecasting method could predict hierarchical problem of rock slope quality more scientific, and it also can provide more reliable basis for adopt economical and reasonable support treatments.
