Problems solved by technology

[0002] During roadway excavation, in order to prevent the top surface of the roadway from collapsing, it is necessary to support the roadway. Therefore, the hydraulic support device is an important mining device. In the existing hydraulic support device, it is still in each operation. There is no hydraulic support device and support method based on the extension of the roadway, which connects the advanced working face of the roadway and the fully mechanized mining working face of the roadway, so as to meet the support requirements of the roadway.

Abstract

A hydraulic support device and supporting method based on extending in roadway, comprising a hydraulic support I (301) disposed at a front end of the roadway, a hydraulic support II (302) disposed ata rear end of the roadway, and a fulcrum connecting device arranged between the hydraulic support I (301) and the hydraulic support II (302) and embedded in the bottom surface of the roadway, throughthe hydraulic support I (301) and the hydraulic support II (302), the roadway is supported and protected, and through the fulcrum connecting device, the hydraulic support I (301) and the hydraulic support II (302) are connected to each other and supported by each other, and are no longer separately supported on the respective working faces, thereby improving the reliability of the roadway support.

Description

technical field [0001] The invention relates to a hydraulic support device, in particular to a hydraulic support device and a supporting method based on extending in a roadway. Background technique [0002] During roadway excavation, in order to prevent the top surface of the roadway from collapsing, it is necessary to support the roadway. Therefore, the hydraulic support device is an important mining device. In the existing hydraulic support device, it is still in each operation. There is no hydraulic support device and support method based on the extension of the roadway, which connects the advanced working face of the roadway and the fully mechanized mining face of the roadway, so as to meet the support of the roadway. [0003] Based on the existing technical problems, technical features and technical effects, the application technical solution of the present invention is made. Contents of the invention [0004] The object of the present invention is a hydraulic suppor...
