The invention discloses a multilayer gently inclined ore body ore-waste separation collaborative mining method. The method comprises the following steps: step 1, mining an ore body, namely mining fromthe lower part of the ore body to the upper part, and forming a goaf at the bottom of the ore body; step 2, treating a waste rock interlayer, namely caving the interlayer adjacent to the ore body into the goaf of the ore body at one time to serve as a goaf bottom filling waste rock layer, and performing isolation treatment on the surface of the waste rock layer; and step 3, continuously mining the orebody adjacent to the caved interlayer in the step 2. According to the invention, safe mining of the multilayer gently inclined ore body is realized; efficient mining and non-waste mining, the hidden danger problems of violent mutual disturbance, difficult interlayer stability treatment and the like in a traditional mining method are effectively solved; the mining preparation cutting workloadis greatly reduced, the mi
