Abstract: According to the working conditions, the site vibration test method, dam risk analysis method, seepage simulation method and stability analysis method are adopted to analyze the tailings dam stability under the action of blasting vibration waves, and determine the main factors that affect the safety of tailings dam, and determine the security boundary conditions of tailing dam under different operating conditions. The research results indicate that, under the proposed vibration conditions the tailings dam is not safe when vibration velocity is 12 cm/s, and 6.0 cm/s is the maximum security allowed vibration velocity.
