description The invention relates to a two-frame one-set centrally placed top caving coal end support. The support comprises a top beam assembly, a base assembly, guide frames, cable hangers and side cantilever beams. The top beam assembly is connected to the base assembly through stand columns. The cable hangers are connected with the top beam assembly. The guide frames and the side cantilever beams are correspondingly arranged on the two sides of the top beam assembly. The top beam assembly is formed by a front beam, a front top beam, a middle top beam and a rear top beam, wherein each of the front beam, the front top beam, the middle top beam and the rear top beam is of a left-right frame structure. The base assembly is formed by the combination of a front bracket, a front base, a middle base and arear base, wherein the front bracket, the front base, the middle base and the rear base are matched with the left-right frame structure of the top beam assembly. The caving coal end support solves the roadway support efficie
