An introduction was made to the operating principle and application of a airlift device used for underwater mining and lifting. The performance of the self-excited oscillation pulsed jet breaker and the airlifting characteristics and the critical water velocity of the device were discussed. The practices of offshore placer mining and down-hole hydraulic mining show that the pulsed jet breaker has a great ability of underwater breaking and agitating, greatly improving the airlift performance. The airlift device features simplicity, high efficiency and good performances in technology and economy.
