Laying method of metal mesh false roof

Abstract

The invention provides a laying method of a metal mesh false roof. The laying method of the metal mesh false roof is used for fully-mechanized coal mining. The laying method of the metal mesh false roof comprises the following steps: fixing the other end of a steel wire rope on the other side roadway of the top wall of a fully mechanized working face and arranging a metal mesh on the top wall of the fully mechanized working face along the width direction of the fully mechanized working face, enabling hydraulic support top beams to abut against the lower side of the metal mesh in sequence, arranging and fixing the steel wire rope on the lower side of the metal mesh in a supporting mode, moving hydraulic supports and enabling space for laying a mesh in next link to be reserved between the hydraulic support top beams and the metal mesh, and repeating the procedures, laying metal meshes on all the working face top walls and connecting the edge of two adjacent metal mesh. The laying method of the metal mesh false roof achieves quick laying of the metal mesh false roof and solves the technical problems that due to the fact that half round wood or a steel pipe and the like must be used to be arranged on the metal mesh in a pressing mode, before laying the metal mesh, the top beams are lowered to form reserved working space, safety cannot be ensured, steps are trivial, working efficiency is low and the like in the prior art.

Description

technical field [0001] The invention relates to a false roof laying technology for fully mechanized mining working faces of coal mines, in particular to a laying method of metal mesh false roofs for fully mechanized mining working faces of coal mines. Background technique [0002] The metal mesh false roof needs to be laid before the fully mechanized mining face is closed to ensure the safety of the inner space of the roadway. A hole in the net, the first rope, this is also the link with the greatest security threat. [0003] The working site of the fully mechanized mining face is often at or close to the abnormal section of the structure, the roof is in poor condition, the coal wall is easy to fall off the roof, and the safety threat is great when the personnel enter the working face; , the geological conditions tend to be harsh, and the roof pressure increases accordingly, all of which are unfavorable factors for the safety of fully-mechanized mining face. [0004] In th...

AI Technical Summary

Problems solved by technology

The top beam of the hydraulic support supports the top wall of the fully mechanized mining face. Before laying the net, the top beam of the hydraulic support needs to be lowered to form a reserved working space so that the operator can lay the metal net on the top beam and lay the metal net on it. Pressing half logs, steel pipes or I-beams, the safety of the reserved work space cannot be guaranteed without the support of hydraulic supports; and the steps are cumbersome and the work efficiency is low
