The invention discloses a gob-side entry retaining method for non-blasting roof-
cutting and pressure releasing of a soft-top
coal seam. The gob-side entry retaining method comprises the following steps that 1, a roof of a reserved entry is reinforced on the side, close to a gob, of the reserved entry through an anchor
rope, and working face advanced mining of anchor
rope reinforcing construction is completed; 2, lanced seam holes are drilled in the side, close to the gob, of the reserved entry and form pre-splitting lanced seams, and working face advanced mining of lanced seam holes drilling construction is completed; 3, anchor withdrawing construction is conducted, working face advanced mining of anchor withdrawing construction is completed; 4, temporary reinforced supporting and stoppingwaste rock supporting are conducted on the reserved entry; and 5, the roof of the gob is collapsed to form a gob-side retained entry, and after the gob-side retained entry is stabilized, the temporary reinforced supporting in the step 4 is withdrawn. According to the gob-side entry retaining method, through drilling of the lanced seam holes, the link of blasting roof-
cutting in original gob-sideentry retaining is substituted, and thus the gob-side entry retaining is
safer; and meanwhile the usage amount of explosives is saved, the cost of gob-side entry retaining is reduced, the
working environment is improved, and it is guaranteed that a gob-side entry retaining technology is safely conducted.
