Problems solved by technology

[0003] The purpose of the present invention is to solve the problems existing in the prior art that monitoring, monitoring and forecasting can only be carried out after geological disasters produce signs. The monitoring and forecasting of geological disasters that have not yet found signs is relatively weak, and it is impossible to implement continuous, real-time and dynamic monitoring. monitoring problems; provide a mine tunnel collapse alarm; simple structure, easy installation, high detection sensitivity, the mine tunnel collapse alarm can implement continuous, real-time, dynamic monitoring of geological disasters such as landslides

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Mine tunnel collapse alarm, combined with figure 1 , including an intelligent detection wire 1, a resistance detector 4, and a computer 5, the intelligent detection wire 1 is connected to the resistance detector 4 through a wire 3, and the resistance detector 4 is connected to the computer 5. The intelligent detection wire 1 is made of titanium-nickel-based memory alloy wire, copper-based memory alloy wire, iron-based memory alloy wire, or titanium-nickel-based memory alloy wire that is in the parent phase no matter in winter or summer. The intelligent detection wire 1 and the wire 3 are connected by welding, or connected by a terminal post 2 .

[0014] Although the specific implementation of the invention has been described above in conjunction with the accompanying drawings, it does not limit the protection scope of the present invention. Thos...

Abstract

The invention discloses a mine tunnel collapse alarm device which comprises an intelligent detection wire, a resistance detector and a computer, wherein the intelligent detection wire is connected with the resistance detector through a lead; the resistance detector is connected with the computer; wiring terminals are arranged on the lead between the intelligent detection wire and the resistance detector; and the intelligent detection wire is connected with the lead in a welding manner or through the wiring terminals. The mine tunnel collapse alarm device has a simple structure, is convenient to mount and high in detection sensitivity, and can be used for continuously and dynamically monitoring geological disasters, such as collapse in real time.

Description

technical field [0001] The invention relates to the technical field of tunnel and mine safety equipment, in particular to a mine tunnel collapse alarm. Background technique [0002] Landslide is a natural phenomenon in which tunnels and mines collapse under the action of natural forces. Roof fall is the fall of the roof rock in the mining space or other working places underground. In mine tunnel construction, sometimes there is no difference between landslide and roof fall, and this kind of natural phenomenon of non-artificial collapse and fall is often described together. Landslides are the most common major geological disasters in mine tunnel construction, accounting for more than 90% of all major geological disasters. For example, in my country's Chengdu-Kunming Line, Daqin Line, Hengguang Double Line, etc., the stoppage caused by landslides accounts for about 1 / 4-1 / 3 of the total construction period. Another example is the Hangzhou Metro Tunnel, which also experienced...
