Thin ore body mining method

The invention provides a thin ore body mining method, which relates to the technical field of mining, and comprises the following steps: constructing an in-vein roadway in a thin ore body along the ore body trend of the thin ore body; an in-vein cutting courtyard crossed with the in-vein roadway is constructed in the thin ore body along the inclination of the ore body of the thin ore body, and an ore body unit area defined by the in-vein roadway and the in-vein cutting courtyard is formed; and spoke-shaped blast holes are formed in the ore body unit areas, and expanding mining is conducted on the thin ore body through the spoke-shaped blast holes. According to the mining method, the effects of ore extraction and surrounding rock protection are achieved through fine hole distribution, charging and blasting, the mining width is flexibly adjusted, the stoping efficiency is high, one-time blasting mining of a stope is achieved, the production capacity is improved, the overall mining period is shortened, and the m
