description	The invention discloses a treatment method for a waste vertical well shaft penetrating through an upper close-distance coal seam stope working face and a lower close-distance coal seam stope working face and belongs to the field of coal mining. According to the treatment method for the waste vertical well shaft, the waste shaft is reinforced, false tops and false bottoms are formed on the penetrated upper close-distance coal seam stope working face and the penetrated lower close-distance coal seam stope working face, and thus equipment can pass safely and smoothly. According to the technical scheme, the treatment method comprises the steps that the parts, at the bottoms of coal mining seams, of the shaft are reinforced in a mode of filling coal gangue and pouring concrete or a mode of arranging a ladder beam and pouring the concrete, and thus the working face false bottoms are formed; the parts, on the tops of the coal mining seams, of the shaft are reinforced in a mode of steel beam supporting and concrete p
