To study the influence of coal mining on the stability of river levees, a mechanical model of mining-induced river levee deformation was established. This was based on the mining-induced deformation characteristics of river levees and the application of a typical surface subsidence function. Meanwhile, a failure criterion was proposed for river levees. Using some examples, the deformation of, and stress distribution through, river levees under the influence of mining were obtained: the maximum tensile stress on the bottom of the river levee was less than the tensile strength, under which circumstance the river levee remained undamaged. Meanwhile, this research analyzed the influence of three factors including the maximum surface subsidence wmax, half-length of surface subsidence basin L, and foundation coefficient k on the stability of river levees. Results showed that reducing the mining height of the working face and the foundation coefficient, and increasing the strike length of the working face could reduce the influence of mining on river levees. These results provided a theoretical basis for predicting the mining-induced deformation and failure of river levees.
