Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coal mine roadway construction, and particularly relates to a supporting device for assisting a roadway tunneling machine. BACKGROUND

[0002] In coal mining operations, the tunneling machine is the core equipment for coal mine roadway tunneling. The geological environment of the coal mine roadway is extremely complex, and many severe safety challenges are hidden therein. For example, the existence of faults causes the rock to break and be unable to withstand, and the stability of the stratum structure is greatly reduced. When the tunneling machine attempts to cross the fault area, it is often prone to dangerous conditions such as machine jamming, which seriously hinders the tunneling process. The cave area significantly changes the stress distribution pattern of the surrounding rock. Furthermore, a large amount of accumulated water and toxic and harmful gases may be present inside the cave, and these factors all bring unpredictable risks to the tunneling operation.

[0003] The current existing support and protection device for roadway tunneling, although can provide partial support and protection for the tunneling machine and the operating personnel to some extent, has obvious limitations in terms of function. They often only focus on the direct support of the tunneling machine itself and the operating personnel, but lack the ability to accurately detect the complex geological environment of the roadway and timely and effective early warning. This means that potential dangers cannot be perceived in advance and timely warnings cannot be issued, which increases the probability of major safety accidents and seriously threatens the life safety of each operating personnel and the property safety of the enterprise, and fundamentally restricts the safe and efficient advancement of the coal mine roadway tunneling project. SUMMARY

[0004] In view of the technical problem that the existing tunneling machine protection device has only a single function of support and protection, and lacks a detection and alarm function, the utility model provides a supporting device for assisting a roadway tunneling machine, which can provide support and protection for the tunneling machine and the operating personnel when the tunneling machine is working, and can also collect information data in the roadway in real time and provide a danger warning.
