Abstract
The embodiment of the utility model discloses a mechanical and blasting mining bracket. The mechanical and blasting mining bracket comprises a top beam and a coal baffle hinged to the top beam, wherein a drive part for driving the coal baffle to unfold or fold is arranged between the coal baffle and the top beam. When the mechanical and blasting mining bracket is adopted in the mechanical mining process, the drive part of the coal baffle drives the coal baffle to be unfolded and fixed to the bottom of the top beam or to be dismounted; and when rocks or irregular coal beds are met and coal blasting needs to be performed, the coal baffle can be unfolded to be in the drooping state through the drive part, and the rear part of the bracket is closed for preventing the coals or the rocks from moldering hydraulic prop coatings in the blasting process so as to effectively protect the props. Moreover, the unfolding or folding action of the coal baffle is controlled by the drive part without manual assistance, so that the flexibility of the coal baffle in running is improved.
