Abstract: Abstract: In order to avoid large area roof weighting and reduce the cost for deep gob-side entry retaining with hard roof, a method for gob-side entry retaining by short-hole blasting and narrow backfill was proposed. The FLAC3D software is used to simulate three kinds of gob-side entry retaining schemes under the width of the backfill. The width of the backfill is determined by comparing the deformation of surrounding rocks. Through theoretical calculation and engineering practice, the blasting parameters of short-hole are determined. The monitoring data of mine pressure show that the method of short-hole blasting and narrow backfill can effectively cut off the side roof of the mining area, so that the remaining lanes can meet the requirements of reuse.
