Filling body low-disturbance blasting method under large-diameter deep hole two-step recovery

The invention discloses a filling body low-disturbance blasting method under large-diameter deep hole two-step recovery, and relates to the technical field of mine blasting. The filling body low-disturbance blasting method under large-diameter deep hole two-step stoping comprises the following specific operation steps: step 1, determining an actual boundary: after stoping in the step 1 is finished, scanning a goaf by utilizing a laser scanning technology, and establishing a goaf three-dimensional model so as to determine the boundaries of ore bodies on two sides; according to the filling body low-disturbance blasting method under large-diameter deep hole two-step recovery, the stress wave propagation range is improved in the mode that the main blasting holes and the buffer holes are arranged in the vertical direction; the intensity of blasting stress waves is reduced by reducing the charge density of the buffer holes; and meanwhile, through the mode of hole-by-hole detonation of the main blasting holes and mi
