Device for monitoring and early warning roof fall disaster of coal mine roadway

Abstract

The invention discloses a device for monitoring and early warning a roof fall disaster of a coal mine roadway, relates to the technical field of roadway roof fall disaster monitoring and early warning, and solves the problem of roadway roof fall disaster early warning. The device for monitoring and early warning the roof fall disaster of the coal mine roadway comprises two groups of main body structures, wherein each group of main body structures comprises two symmetrically installed main body structures; foundations are installed on the lower end faces of the main body structures; bearing plates are installed on one sides of the foundations; a fixing mechanism is installed between every two main body structures; a detection mechanism protective cylinder is installed on the upper end faceof each fixing mechanism; a quality detection mechanism is installed on the upper end face of each detection mechanism protective cylinder; each main body structure comprises two prefabricated side plates, limiting edges, a prefabricated top plate, matching clamping grooves, inner supporting plates, fastening bolts, connecting bases, T-shaped grooves and reinforcing ribs; and the matching clampinggrooves are arranged on the upper end faces of the prefabricated side plates. The device for monitoring and early warning the roof fall disaster of the coal mine roadway has the function of early warning of a mine tunnel collapse disaster and the effect of isolating hazards.

Description

technical field [0001] The invention relates to the technical field of coal mine roadway roof fall monitoring and early warning, in particular to a coal mine roadway roof fall disaster monitoring and early warning device. Background technique [0002] With the rapid development of the mining industry, the requirements for mine roadways are getting higher and higher, and the factors that aggravate the hidden dangers of roof fall in the roadway are also increasing. The increase of the mine pressure leads to the increase of the mine pressure; the increase of the mine pressure and the complex geological conditions make the support more difficult. Therefore, the monitoring and early warning of roadway roof fall is very important. [0003] However, the existing roof fall disaster monitoring and early warning structure is single, the function is insufficient, and it cannot provide early warning and alarm in time to help evacuation. When in use, it cannot fix the inner wall of the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a coal mine roadway roof fall disaster monitoring and early warning device to solve the problem that the structure of the roof fall disaster monitoring and early warning proposed in the above background technology is single, the function is insufficient, and the early warning and alarm cannot be timely, and the evacuation can be helped. Fix the inner wall of the mine tunnel, reduce the possibility of mine tunnel collapse, and support the falling slag to avoid blocking the mine tunnel and other issues
