Abstract: Gob side entry retaining is an important pillarless roadway protection technology in coal mining. It can not only increase
the recovery rate of resources, but also reduce the amount of excavation in the mine. At present, many mines have implemented
gob side entry retaining and achieved good economic benefits. This paper introduced the basic concepts and influencing factors of
gob side entry retaining and analyzed the development status of construction and supporting technology for gob side entry retaining,
which can provide certain reference for a deep understanding of gob side entry retaining.

Key words: gob side entry retaining; pillarless roadway protection; shed support; flexible concrete support
