Embodiment Construction
[0029] Orientation terms such as upper, lower, left, right, front, rear, front, back, top, bottom, etc. mentioned or possibly mentioned in this specification are defined relative to the configurations shown in the drawings, the word "" "Inner" and "outer" refer to directions toward or away from the geometric center of a particular component, respectively, and they are relative concepts, so they may vary accordingly according to their different positions and different states of use. Therefore, these and other terms of orientation should not be construed as limiting.
[0030] like figure 1 As shown, the present application provides a method for supporting a fully mechanized mining face, comprising the following steps: S1: setting a support table 32 on the coal wall 31 of the roadway 3; S2: setting a support 1 for supporting the roadway 3, the The bracket 1 includes a guard board assembly 10 and a top beam 11 connected to each other, and a telescopically arranged upright column ...

The invention discloses a method and a device for supporting a fully mechanized mining face. The supporting method for fully mechanized mining face includes: arranging a support platform on the coal wall of the roadway; setting up a bracket for supporting the roadway, the bracket includes a connected guard plate assembly and a top beam, and a telescopic arrangement is installed on the guard plate assembly The upright column is pressed against the support platform to push the guard plate assembly against the coal wall, and push the top beam against the roof of the roadway. The fully mechanized face support device is used to implement the fully mechanized face support method. The method and device for supporting the fully mechanized mining face provided by the present application improve the support force of the telescopic roof beam at the front end of the bracket to the roadway roof, increase the support force of the guard plate to the coal wall, and avoid the occurrence of coal mining face. The problems of subsidence and gangs increase the safety of the mining process.
Description
technical field [0001] The present application relates to the technical field of coal mining, in particular to a method and device for supporting a fully mechanized mining face. Background technique [0002] In the process of coal mining, the bracket supports the roof of the roadway through the roof beam, and supports the sidewall of the roadway through the guard plate to control the mine pressure of the coal mining face. [0003] Under the condition of super high mining height, the existing support technology has the following shortcomings: First, the upward force of the support column cylinder mainly acts on the back half of the top beam, and the support effect on the telescopic top beam at the front end of the support is small. As a result, the telescopic roof beam at the front end of the bracket is insufficient to support the roof of the roadway, and the coal mining face has the risk of collapse. The risk of help increases and the safety of the mining process is reduced...
