Using quartz sands to simulate the work condition, the experiment on the factors of sand lift which influences the lift effect in borehole hydraulic equipment is carried out. The experiment results show that there is an optimum distance between the intake and mineral deposit; under the condition of the same air input capacity; the lifting capacity increases with the submergence proportion; different installation angle of the water nozzle influences the effect of the sand lift; there is an optimally installation angle of 10 degrees between nozzle axial lead and tangential direction of the lift pipe wall; the number of air nozzles affect lifting capacity; the optimally installation nozzles number is 3; and whether fitting stir nozzles or not is the key factor which determines lifting success.
