Description

Technical Field

[0001] The utility model belongs to the technical field of roadway engineering, and particularly relates to a protection structure for the front wall of a roadway engineering section. Background Technique

[0002] Roadway engineering mainly refers to the roadway construction carried out in mines and underground projects for the extraction and transportation of mineral resources. Its core purpose is to provide safe and effective passageways for the entry and exit of personnel, equipment, ore and other materials. The types of roadways include vertical shafts, horizontal roadways and inclined shafts. Among them, vertical shafts are usually used for the up and down transportation, ventilation and drainage of ore, horizontal roadways are mainly used for the extraction of ore bodies and the transportation of ore, and inclined shafts are suitable for the extraction of ore bodies with larger dip angles.

[0003] In engineering design, geological conditions, the use of roadways and the efficiency of the transportation system need to be considered. In terms of construction technology, blasting technology is mainly used for excavation, and at the same time, support design is required to maintain the stability of the roadway. Common methods include anchor bolts and shotcrete. In addition, the design of the ventilation system is also crucial to ensure air circulation in the roadway and reduce the accumulation of harmful gases.

[0004] Safety management is an indispensable part of roadway engineering. Strict safety standards need to be followed to prevent accidents such as cave-ins, explosions and poisoning by toxic gases. With the development of technology, more and more automation and digital technologies are applied to roadway engineering, such as unmanned aerial vehicle surveys, sensor monitoring and data analysis. These new technologies not only improve the engineering efficiency but also enhance the safety. Generally speaking, roadway engineering occupies an important position in mine development and is the basis for realizing safe and efficient mining.

[0005] The existing protection structure for the front wall is generally installed in the cross-section working area of the roadway engineering by a fixed structure. After one operation is completed, it needs to be disassembled for the next cross-section operation. The disassembly and installation are rather troublesome, and the adjustment performance of the protection structure for the front wall is not good, and the applicability is poor. For this reason, we propose a protection structure for the front wall of a roadway engineering section to solve the above problems. Content of the Utility Model
