Dynamic Calculation And Analysis on The Effect of Mine Blasting Vibration to Tailing Dam
A large number of mining tailings pond were built in the upstream of the stope close neighbor to it, those distance is between 200 to 400m. The tailings dam constructed at upstream is always in underconsolidated, and has low density and loose structure, the liquefied zone appears easily in the effect of mining blasting, and then the dam body is instability. Aiming at one tailings dam of mining corporation, the horizontal vibration acceleration produced by mining blasting is field measured, then the measured data is adopted as the input ground vibration wave, and the response of tailing dam is analysed with dynamic finite element method. The analysis result shows that the response of the latter accumulation dam is larger than that of initial dam, and there is no liquefied zone in tailing dam under blasting vibration. Therefore, it can be regarded that the current production blasting scale does not produce bad influence to the stability of dam body. It provide a reference for the similar engineering in the future.
