The invention relates to the field of underground mine mining process, especially to an open stope-caving combined mining method suitable for mining minerals of which the orebody inclination angle is between 60 DEG and 90 DEG and the thickness is less than 10m. The method is characterized in that each mining ore block consists of a support pillar, an open-stope caving sublevel and a roadway thereof, a caving recovery sublevel and a roadway thereof, an ore chute and the like, wherein the open-stope caving sublevel is arranged along the strike direction of the orebody. The mining scheme has the advantages of simple process, safe production, low cost, high production efficiency, low loss and dilution and the like and is easy to manage. The ore recovery ratio of ore blocks is increased to 75% from about 50%; the ore dilution rate is controlled below 15%; and the mining production capacity is improved from the current 200 tons per day to 350 tons per day. With the gradually reduced thick and large orebodies which are easy to exploit, the requirement on efficiently mining thin ore bodies is more and more urgent, and therefore the method of the invention has very strong competitive power in the mining technical field at home and abroad and has broad application prospect.
