Abstract
In recent years, landslides triggered by underground mining have attracted much attention because of their high hazards and difficulties in prediction and forecasting. How to quickly and accurately determine the potential shear slip surface in locked rock mass ofgently inclined counter tilted rock slope under mining action is crucial for the prevention and control of this type of landslide hazard. In this study, the deformation and damage characteristics of gently inclined counter tilted rock slope under mining action are investigated by numerical simulation, theoretical analysis and physical test, using the Meidong Slope as a prototype, the mathematical equations describing the damage of mining disturbance of slope are established, and a prediction model of the shear slip surface in locked rock mass ofthe slope is proposed. The results show that the prediction model can accurately determine the shear slip surface of the locked rock mass of the slope, the reinforcement of the locked rock mass is the key area for the prevention and control of this type of landslide disaster, and the results of the study can provide a reference for the prevention and control of the geologic disaster of the mountain instability induced by underground mining on gentle anti-dip rocky slopes.
