The invention discloses a multilayer inclined ore body ore and waste separation collaborative mining method. An interlayer serves as an ore body in the ore body mining process, the mining is conductedaccording to the continuous thick large ore body, a conventional low-efficiency layered independent stoping mode is changed, a high-efficiency deep hole is adopted to conduct rock drilling, the ore body and the interlayer are orderly caved by themselves, the ore which is caved is completely sent out, and the waste rock of the interlayer which is caved is reserved at the bottom of the interior ofa stope and serves as the filling waste rock. The footwall ore body is extracted, then a goaf region which is reserved by the mining of the bottom ore body is utilized to serve as a free space, the interlayer is caved at one time, the waste rock which is caved is completely reserved inside the goaf region, the surface of the waste rock is treated, and the ore and waste separation is achieved. Thegoaf region which is formed
