The invention discloses a method for predicting the position of a hydrothermal solution nozzle of a jet deposition ore deposit. The method comprises the following steps: 1, determining a mineralization period and a mineralization stage of the ore deposit; 2, determining the total thickness of the ore body and the thickness of the ore body in each mineralization stage determined in the step 1 through a drilling method, a groove detection method and an underground engineering field measurement method in sequence; 3, modeling on a computer, and restoring the total thickness of the ore body and the thickness of the ore body in each mineralization stage; 4, coupling the total thickness of the ore body and the thickness of the ore body in each mineralization stage, and marking an abnormal area;5, preliminarily correcting the position of the hydrothermal solution nozzle according to the structure in the ore deposit; 6, correcting the position of the hydrothermal solution nozzle again according to the mineral composition in the ore; and 7, predicting the position of the hydrothermal solution nozzle. According to the method, the hydrothermal solution nozzle position is predicted through the macroscopic index ore body thickness, the ore deposit structure and the microcosmic index mineral composition, the method has the advantages of integrity, high efficiency, controllability, uniformity and the like, the situation that the hydrothermal solution nozzle position is predicted through a single index is improved, and the prediction effect is good.
