I-shaped tray and gob-side entry retaining gob side supporting structure

The invention relates to an I-shaped tray and a gob-side entry retaining gob-side supporting structure, belongs to the technical field of gob-side entry retaining coal-pillar-free mining, and solves the problems that an existing anchor rod tray cannot control the stability of the gob-side supporting structure and cannot effectively resist and limit inclination or toppling of the gob-side supporting structure. The I-shaped tray comprises tray bodies and a web plate, the tray bodies are rectangular plates, the two tray bodies are parallel to each other, and the web plate is located between the two tray bodies and is perpendicular to the tray bodies. The I-shaped tray is used for a gob-side entry retaining gob-side supporting structure and can be cooperatively controlled with the supporting structure, inclination or toppling of the gob-side supporting structure is effectively resisted and limited, and therefore the gob-side entry retaining effect is remarkably improved. 本发明涉及一种工型托盘及沿空留巷采空侧支护结构，属于沿空留巷无煤柱开采技术领域，解决
