The utility model discloses a novel tunnel tail support for fully mechanized caving faces. The novel tunnel tail support comprises a base, a main top beam, a caving shield, a front connecting rod, a rear connecting rod, a standing column and a balancing jack. The bottom of the standing column is hinged with the base, and the top of the standing column is hinged to the main top beam. Two ends of the front connecting rod and two ends of the rear connecting rod are connected with the base and the caving shield respectively. The main top beam is hinged with the caving shield. Two ends of the balancing jack are hinged to the main top beam and the caving shield respectively. The novel tunnel tail support is characterized in that side protective plates are fixed on two sides of the main top beam. Gangue blocking protective plates are connected below the side protective plates. The novel tunnel tail support has the advantages that gangue from the rear of the support can be blocked from entering in the support; and working conditions of working face conveying ends are improved, so that operation efficiency can be improved efficiently, labor intensity of workers can lowered effectively. In addition, sufficient space is provided for the rear scraper conveyor cross lateral unloading nose and the vertical direct connecting drive part, and accordingly support strength of the working face conveying ends can be guaranteed.
