Abstract: The gob side entry retaining technology has solved the problem of coal resource waste in underground mining, improved
the maintenance mode and ventilation form of the roadways in the working face, eased the replacement tension between underground
mining and excavation, was conducive to safe and efficient mining of coal mines, and improved the social and economic benefits
of coal mines. However, gob side entry retaining needs to experience the influence of twice mining and periodic weighting during
the period of entry retaining, so the mine pressure behavior is very severe, and the roadway maintenance is more difficult. Based
on this, through improving the support parameters in the gob side entry retaining, applying flexible formwork concrete filling, and
improving the strength of the roadway support body, the stability of the surrounding rock of the gob side entry retaining can be
maintained better, which can provide a certain reference for the support of the gob side entry retaining under similar conditions in
the future.

Key words: coal mine; gob side entry retaining; surrounding rock control
