High rock burst roadway supporting system based on underground soft rock replacement technology

Abstract

The invention relates to a high rock burst roadway supporting system based on an underground soft rock replacement technology. The high rock burst roadway supporting system based on the underground soft rock replacement technology comprises a roadway, wherein a first supporting layer is arranged on the side surface of the roadway, a bottom plate is arranged at the lower end of the first supporting layer, a plurality of groups of slots are formed in the lower surface of the bottom plate, and a plurality of groups of vertical plates are fixed on the lower surface of the bottom plate; limiting rods are fixed to the upper parts of the opposite surfaces of the multiple groups of vertical plates, limiting grooves are formed in the two sides of the upper surface of each limiting rod, limiting blocks are fixed to the upper parts of the opposite surfaces of the multiple groups of vertical plates, multiple groups of baffles are arranged on the lower surface of the bottom plate, the multiple groups of baffles are arranged among the multiple groups of vertical plates correspondingly, and sliding rods are fixed to the two sides of the side surfaces of the baffles. The high rock burst roadway supporting system based on the underground soft rock replacement technology has the beneficial effects that the baffles are used for dividing the rheological rock mass, a constructor can rapidly and conveniently remove the rheological rock mass, construction is safe and convenient, the baffles can be reset after removal, damage to the first supporting layer is avoided, and completeness of the supporting structure is guaranteed.

Description

technical field [0001] The invention relates to a high-impact rock pressure roadway support system based on underground soft rock replacement technology, and belongs to the technical field of underground roadway engineering support equipment. Background technique [0002] In the high-stress complex structure area of ​​deep mines, replace the super soft rock and expansive rock mass in the superficial part of the surrounding rock of the roadway, especially the extremely soft rock and expansive rock on the bottom corner and floor, and loosen and rheologically under the action of external force Part of the rock mass is removed and replaced with shotcrete to replace some of the easily expansive rocks such as kaolin, montmorillonite, and illite, which can greatly reduce the expansion pressure caused by the superficial and initial stages of the expansive rock. Replacing a part of extremely soft rock, that is, muddy cement, rock with low tissue maturity and structure maturity, is be...

AI Technical Summary

Problems solved by technology

[0003] When removing the loose and rheological rock mass at the bottom corner, it is necessary to implement the first roadway support in advance to ensure the safety of the constructor. However, before construction, the support at the lower end needs to be destroyed , leading to certain safety hazards in construction, and in the process of construction, it is easy to cause loose or rheological rock mass lack of support above, causing a certain degree of shedding, affecting the life, health and safety of the constructors
