Zusammenfassung:The invention provides a mining method of a gently inclined thin ore body, which comprises the following steps: arranging a main haulage roadway and an in-vein haulage roadway according to the inclination angle of the ore body, the in-vein haulage roadway is communicated with the main haulage roadway, the inclination angle of the main haulage roadway and the inclination angle of the in-vein haulage roadway are both less than or equal to 12 degrees, and the main haulage roadway is communicated with the in-vein haulage roadway; panels are divided on the two sides of an in-vein haulage roadway in the ore body trend, the length of each panel is larger than or equal to 500 m, the width of each panel is larger than 200 m and smaller than 300 m, and the panels are mined in the ore body trend or in the ore body tendency direction. The mining method of the gently inclined thin ore body is convenient for large-scale mechanical continuous mining operation and has the advantage of high mining efficiency. 本发明提出一种缓倾斜薄矿体的采矿
