Problems solved by technology

[0003] In the process of mining without coal pillars, gangue retaining devices are usually required to support the side of the roadway. The existing gangue retaining devices mainly include multiple metal meshes, scalable U-shaped steels, single supports and side support supports. When in use, It is necessary to lay metal mesh, U-shaped steel and side protection brackets at the junction of the roadway behind the working face support and the goaf, and it is necessary to connect each component together. After the mining is completed, each component will be withdrawn one by one. The laying steps are cumbersome and uniform. Manual operation is required, the degree of mechanization is low, and the progress of the project is slow

Abstract

The invention provides a blocking gangue system, a blocking gangue device and a roadway support method and relates to the technical field of coal mining equipment. The blocking gangue device comprisesa lifting column, a top plate and a side plate, wherein one end of the lifting column is fixed on a base plate; the top plate is connected to one end, far away from the base plate, of the lifting column and extends outwards in the radial direction of the lifting column; the top plate can synchronously lift with the lifting column; the side plate is connected between the base plate and the top plate, is positioned at the end parts, on the same side of the lifting column, of the top plate and the base plate, and can synchronously lift with the top plate; the side plate is used for propping against the side wall of a roadway and provides side support for the side wall of the roadway; and the side plate comprises a first side plate and a second side plate, wherein the first side plate is connected to the end part of the top plate, extends to the direction, close to the base plate, of the top plate and can synchronously lift with the top plate. The blocking gangue system and the blocking gangue device have the advantages that the structure can be simplified, and the project progress can be accelerated.

Description

technical field [0001] The disclosure relates to the technical field of coal mining equipment, in particular, to a gangue-blocking system, a gangue-blocking device, and a method for roadway support. Background technique [0002] With the rapid development of the economy, the demand for coal resources is increasing. In order to conduct coal mining more efficiently and improve the recovery rate of coal, the method of mining without coal pillars is widely used. [0003] In the process of mining without coal pillars, gangue retaining devices are usually required to support the side of the roadway. The existing gangue retaining devices mainly include multiple metal meshes, retractable U-shaped steels, single supports and side support supports. When in use, It is necessary to lay metal mesh, U-shaped steel and side protection brackets at the junction of the roadway behind the working face support and the goaf, and it is necessary to connect each component together. After the minin...
