Abstract: Aiming at the deficiencies of the backward technology, low efficiency and poor reliability of gob-side entry retaining in
underground coal mines, this paper proposed a new technology for gob-side entry retaining in underground coal mines, and
analyzed the technical schemes such as advanced bolt and cable reinforcement support, roof blasting pre-splitting technology and
single-prop strengthening support in detail. The actual application in the Yuecheng Coal Mine of Qinxiu Coal Industry Co., Ltd.
shows that the new technology for gob-side entry retaining in underground coal mines is of good reliability and high stability,
which is of great significance for improving the safety and construction efficiency of gob-side entry retaining in underground coal
mines.

Key words: gob-side entry retaining; reinforcement support; blasting pre-splitting; single-prop support
