Explosion Experimental Study Based on the Small Tailings Pond Model

Abstract:

Explosion experiment was implemented on the small tailings dam model, aims to study the explosion effect of tailings sand under the action of the explosion. Explosion experiment includes three phases; experimental points were set respectively in the starter dam, embankment and deposited beach. In this experiment, blasting vibration velocity and vertical displacement of sand body are measured and collected, so did the tailings sand’s moisture content, cracks’ size, blasting crater, water and sand spurt phenomenon. Experimental results show that the buried conditions and tailings dam’s moisture content have a significant impact on explosion effect. By processing the velocity and displacement data, the attenuation law of blast vibration velocity in the tailings dam is reached, the blasting vibration velocity corresponding to crack damage of sand body is predicted, and the relationship between failure phenomenon of the tailings dam and the displacement produced by explosion is obtained.
