Abstract The bedding rock slope was studied in order to effectively predict its deformation and failure induced by underground mining in mountainous area based on the probabilistic integration on mining subsidence of horizontal surface. A model for predicting the subsidence and deformation of bedding rock slopes was established under the condition of unit mining and semi-infinite mining and a calculation process was presented. The predicted results were compared with the data from field test and physical modelling test. The predicted results are in good agreement with the measured data of subsidence. The shape of the predicted subsidence curve is similar to that from the physical modelling test and they have the same maximum values of subsidence.
