Experimental Analyze of Blasting Effects on Dry-Beach in Abandoned Tailings Dam

Abstract:

In order to study liquefaction and failure law of the tailings under the action of blasting vibration, series blasting experiments were done in dry beaches of a small abandoned tailings dam. The explosives was buried in the tailings dry beach face, blasting created blasting crater and arc shaped cracks, and accompanied by sand boil and water eruption. By installing blasting vibration velocity and acceleration sensors on tailings dam dry beach to measure corresponding blasting vibration velocity and acceleration, regression analyses on experimental data, the blasting vibration velocity and acceleration which can cause tailings sand liquefaction and damage are respectively 23.94cm/s and 4.38m/s².
