Description

Technical Field

[0001] The present invention relates to the technical field of protective devices, and in particular to a protective device for underground construction of mining engineering. Background Art

[0002] During the underground construction of mining projects, the underground environment is often full of dangerous factors, such as roof collapse, vibration, air pollution and other problems. The safety of construction workers and the comfort of the working environment are the key factors that must be considered in mining operations. In order to deal with these potential risks, various protection and safety devices have been widely used.

[0003] Traditional mine roof protection devices mainly provide protection through supporting structures and simple shock-absorbing facilities, but these devices usually have some shortcomings, such as poor shock absorption effect, inability to effectively prevent the roof from shaking or collapsing violently, inability to achieve more intelligent adjustment functions, and lack of effective solutions for air circulation and temperature regulation in the underground environment. In the prior art, there is a lack of a comprehensive device that integrates protection, shock absorption, air circulation, temperature regulation and stable support.

[0004] In order to improve these problems, modern mining engineering technology has proposed a variety of new protection schemes. One of the more advanced methods is to achieve comprehensive protection by setting multiple movable protective plates, shock-absorbing springs, mobile plates and supporting devices on the roof. Through reasonable design, the mine roof can be effectively supported and buffered when it is vibrated, and can be automatically adjusted according to actual conditions to enhance the adaptability and stability of the protective device. Although the protective devices on the market can protect the roof safety during mine construction to a certain extent, there are still some problems, such as unclear shock absorption effect, complex structure, large size and poor air circulation.
