Abstract

The embodiment of the invention provides supporting equipment. The supporting equipment comprises a support and a rear tail beam assembly; the support comprises a top beam structure and supporting columns; one ends of the supporting columns are connected to the top beam structure, and the other ends of the supporting columns are used for directly abutting against the ground of a roadway. the rear tail beam assembly comprises a coal baffle and a telescopic column; one end of the telescopic column is connected to the tail part of the top beam structure, and the other end of the telescopic column faces the ground of the roadway; and the coal baffle is connected to the telescopic column and can ascend and descend along with stretching and retracting of the telescopic column. According to the embodiment, a top mine can be recycled, waste is reduced, and the mining rate of coal mine resources is increased.

Description

technical field [0001] The present application relates to the technical field of coal mining, and in particular, the present application relates to a supporting device. Background technique [0002] In the process of coal mining, the end of the coal mining face and the roadway all need to use support equipment. [0003] The rear of the current support equipment is the gangue tail beam, there is no coal discharge port for the top coal to slip out, and the lower part of the support equipment has a large-sized chassis, which cannot provide transportation for the transport aircraft to extend to the rear of the support equipment. Therefore, the top coal cannot be recovered, resulting in a large amount of coal resources being thrown into the goaf, which is a huge waste. Contents of the invention [0004] In view of the shortcomings of the existing methods, the present application proposes a support device to solve the technical problems of the prior art that the top coal cannot...
