Problems solved by technology

The patent application describes grouting the broken surrounding rock to form a reconstructed bearing arch, combined with the use of the deep crushing area to relieve pressure and absorb energy to consume the dynamic load formed by mining, further reduce the crushing effect of mining on the surrounding rock, and ensure the roadway surrounding rock Stable roadway surrounding rock control method, which uses the traditional grouting + bolt, anchor cable + anchor net + steel belt for support, which cannot fully cope with the support capacity required for deformation and damage to the roadway, as well as the subsequent secondary maintenance costs, etc.

Abstract

The invention discloses a repairing method and a roadway structure of a deformation damaged roadway, which are mainly suitable for the repairing construction of deep roadway and soft rock roadway with serious deformation and damage of surrounding rock. The new roadway repair technology consists of six parts: roadway investigation, cementation and solidification of deformed roof, removal of bulging surrounding rock, cementation and solidification of floor, surface sealing of roadway surrounding rock, and detection and maintenance of surrounding rock activity. The invention firstly cements and solidifies the deformed roof, so that the roadway repair operation can be carried out safely under the protection of the integral roof with a certain thickness, and the road repair efficiency is improved; The overall strength and bearing capacity of the surrounding rock are greatly improved; after the repair, the surrounding rock of the roadway is complete and stable within the service life, and it does not need to be repaired again; the construction process is simple and easy, the comprehensive cost is low, and the operation is safe.

Description

technical field [0001] The invention relates to a repairing construction technology for an underground deformation damaged roadway, in particular to a repairing method for a deformation damaged roadway and a roadway structure. Background technique [0002] At present, the surrounding rock of deep mining roadway and soft rock roadway often undergoes continuous deformation and damage, which makes the roadway section continue to shrink. In order to ensure the use function of the roadway, it is necessary to brush the large roadway section and carry out the roadway support again. Existing roadway repair technologies mostly use anchor rods, anchor cables, metal meshes, metal retractable supports, sprayed concrete, wall backfill and other methods and their combined support. These supports often cannot completely control the deformation and damage of the surrounding rock. After the roadway is repaired, the surrounding rock is still in the process of continuous deformation and damag...
