The invention discloses an overburden strata low dilution ore drawing quantitative control method which includes that the segmentation height H is determined according to ore body conditions and equipment capability; when ore drawing spheroids (1) are tangent pairwise, the distance between adjacent ore drawing openings (2) is the access distance L; the longitudinal half axis length of the ore drawing spheroids is recommended for the ore drawing step pitch; ore drawing control is performed by aid of the cubic function relation between the height x of a drawn body and the weight y of the drawn body; a physical stereoscopic model and a Power Factor Correction (PFC) 3d numerical model are constructed according to several groups of recommended stope structure parameter combinations, ore drawing simulations are performed respectively, and the optimum parameter combination is preferred. The stope structure parameters are determined on the basis of practically measuring the mine ore drawing spheroids, and the control method has strong pertinency and high reliability; demonstration and preference are performed in the mode of combining physical simulation and numerical simulation, accordingly the optimum parameter combination and the optimum ore drawing mode are determined, the whole technique of stope structure parameter preferring in a caving method and overburden strata low dilution ore drawing is obtained, and ore drawing scientificity and reliability are improved.
