Study on Blasting Effect on Tailings Pond

In order to study the liquefaction and damage oftailing sands under blasting vibration, series of explosionexperiments were done in the experimental tailings pond. Theexplosives are buried in the tailings dry beach. Explosionscreated blasting crater, arc shaped regular cracks, andaccompanied by sand boil and water eruption. The blastingvibration velocity and acceleration sensors are set in the tailingsdry beach and dam body and to measure the blasting vibrationvelocity and acceleration. Regression analyses on experimentaldata, the blasting vibration velocity which can cause tailings sandliquefaction and damage are respectively 23.94cm/s. This resultcan be used as reference to safety allowable vibration speed oftailings dam under blasting vibration effect.
