The invention discloses a mining method for a mechanized mining working surface end and a corresponding end support bracket. The end support bracket comprises a base, a connecting rod, a covering beam, a top beam, a three-level side protecting board, a stand column and a side supporting plate; and the mining method for the mechanized mining working surface end comprises the process of fixing the height of a coal mining machine barrel, conducting coal mining at the end, supporting the end by the end support bracket so as to lead the side support plate of the end support bracket to be vertical to a mechanized mining working surface, and protecting the coal wall of the end laterally. By virtue of the end support bracket and the mining method for the mechanized mining working surface end, theoperation difficulty of operators is alleviated, the phenomenon of mutual engagement between brackets is avoided, triangular coal is eliminated, and the recovery ratio of coal resources is improved.
