Anti-impact airtight device of integrated goaf monitoring system

Abstract

The invention belongs to the field of coal mine goaf disaster prevention and reduction and relates to an anti-impact airtight device of an integrated goaf monitoring system. The anti-impact airtight device is composed of a shear thickening material airbag wall and a disaster monitoring system, the shear thickening material airbag wall comprises a shear thickening material layer, a supporting airbag, an air pressure monitoring device and an inflation component, and the disaster monitoring system is composed of a corresponding sensing component, an online display device, a signal diverter and an information transmission system. The device is made of an anti-impact material and can realize quick sealing of a goaf. A novel material is adopted, so that quick sealing can be realized, and the anti-impact airtight device has good fireproof and anti-explosion functions; collection, analysis and pre-warning of disaster factors of the goaf can be realized through the monitoring system so as to accurately and clearly acquire related status of the goaf, and powerful support can be provided for disaster prevention and reduction of the mine goaf.

Description

technical field [0001] The invention belongs to the field of disaster prevention and reduction in coal mine goafs, and relates to an isolation facility involving the application of new materials for mine disaster visualization monitoring and disaster reduction, in particular to an anti-shock airtight device integrated with a goaf disaster monitoring system. Background technique [0002] After the coal mine mining face advances to the stop production line, the working face will be moved and the goaf will be closed in time. At present, the commonly used methods of closing gobs include brick masonry and grout filling. The former mainly uses masonry, cement and other materials to artificially build a closed wall, and the latter uses filling bags by erecting special filling bags in advance. The cement slurry method is used to construct the airtight wall. The main problems currently existing in the two are that the construction process is complicated, the labor intensity of the ...

AI Technical Summary

Problems solved by technology

[0003] The technical problems in the prior art solved by the present invention are: the construction process is complicated, the labor intensity of the workers is high, the project quality is easily affected by the workers' operation level, especially the method of slurry filling has the problem of difficulty in connecting the roof, and the sealing of the gob The effect is poor; at the same time, problems such as water accumulation and temperature in the goaf cannot be detected, the gas detection and analysis results have large errors, and the operation process is relatively cumbersome, so it is impossible to realize real-time monitoring of disaster factors in the goaf
