The invention discloses an anti-blocking technique for stored ores of a high orepass during phosphate ore mining. A vibration table is arranged at an upper opening of the orepass; a vibration rod downwards stretches into the orepass, and when the vibration table works, the vibration rod is used for vibrating slag in the orepass. The technique is simple; the vibration rod is installed in the orepass directly; when the orepass is not blocked, a vibration facility does not need to be started; when vibration dredging is needed, a starting button is operated, and therefore operation is easy; and the safety and reliability coefficients are high, and the slag is loosened and discharged directly through small-amplitude vibration of a steel pipe.
