Problems solved by technology

[0002] In the process of coal mine mining, due to the super high height along the channel, the highest point reaches 7.6m, the hydraulic support of the advanced support section of the coal mining face and the along channel cannot form effective support, resulting in that when the working face is mined to the super high section, the advanced support cannot effectively support Roof protection, the overlying coal seam is affected by mining and periodic pressure, it is easy to cause roof accidents, and there are major safety hazards

Abstract

The invention provides an overall laying method for an artificial roof. The overall laying method comprises the following steps that a first wood crib is formed along a crossheading top plate in a sleeper stacking and inserting mode for top sealing; a plurality of first I-shaped steel are arranged below the first wood crib at intervals, and the first I-shaped steel is suspended and fixed to a crossheading top plate through first anchor cables to form a first false top layer; the metal net is laid below the second false top layer to form the artificial false roof structure, the first false top layer formed by the wooden sleeper, the first I-shaped steel and the first anchor cable is fixedly connected with the gate road to form a whole, and the second false top layer is arranged below the first false top layer, so that a support is convenient to support, obvious deformation and displacement do not occur in the operation period, and the working efficiency is improved. The safety is greatly improved, the occurrence of roof fall accidents is effectively avoided, and the safety and reliability of the working environment are ensured.

Description

technical field [0001] The present application relates to the technical field of coal mining, and in particular, to a method for laying an artificial false roof as a whole. Background technique [0002] In the process of coal mining, due to the superelevation of the trough, the highest point reaches 7.6m, and the hydraulic support of the advanced support section of the coal mining face cannot form an effective support with the trough, which leads to the failure of the advanced support to effectively support the working face when the mining face reaches the superelevation section. The roof guard and the overlying coal seam are affected by mining and periodically pressed, which is likely to cause roof accidents and cause major safety hazards. SUMMARY OF THE INVENTION [0003] The present application aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the purpose of this application is to propose a method for...
