Method for recycling studs at boundaries of ore bodies and treating goaf

The invention relates to an ore body boundary stud recycling and goaf processing method, which comprises the following steps of: (1) designing a medium-length hole construction drawing and finishing construction according to the drawing according to the sequence of blasting planned in the later period and the difficulty degree of blasting in combination with the existing medium-length hole blasting parameters of a mine when a subsection rock drilling stage open stope method is adopted for mining; (2) segment division: taking a single-side goaf as a free surface, and performing segment division on the fan-shaped medium-length holes one by one according to hole numbers so as to enable the interval columns to be detonated according to an expected design arrangement or a hole number sequence by utilizing a millisecond time interval of a millisecond nonel detonator; (3) construction organization design is completed, the number of detonator sections is designed according to section position division, and concentrat
