Real-time active detecting and passive monitoring integrated system and method for hidden disasters of mine

Abstract

The invention discloses a real-time active detecting and passive monitoring integrated system and method for hidden disasters of a mine, and belongs to hidden disaster monitoring systems and methods for mines. The system mainly comprises electrodes, electrode treatment controllers, an electrical prospecting apparatus main unit / communication substation, a ring network and a monitoring center. The system performs electrical prospecting active detection regularly, one electrode treatment controller is taken as source emission current through the corresponding electrode, an active electric field is formed in coal and rock mass, the other electrode treatment controllers receive active voltage signals synchronously through the corresponding electrodes, and active emission is performed sequentially one by one; passive potential signal monitoring of the coal and rock mass is performed at other time. An evolutionary process of the hidden disasters of the mine is reflected through coupling of results obtained through active electrical prospecting detection and passive potential monitoring, and meanwhile, real-time risk detection and evaluation of a dynamic disaster region and real-time fusion early-warning of risks before disasters are realized. The system and the method can reflect the evolution information of an internal structure of the coal and rock mass in real time more comprehensively, the anti-interference capability is high, and the early warning accuracy is high.

Description

technical field [0001] The invention relates to a system and method for monitoring hidden disasters in mines, in particular to a system and method for integrating real-time active detection and passive monitoring of hidden disasters in mines. Background technique [0002] With the continuous increase of mining depth, the ground stress, ground temperature and gas pressure are getting higher and higher, and the impact of mine mining is becoming more and more significant, such as rock burst, rock burst, coal and gas outburst, water inrush and internal fire Such hidden disasters are regional, process, sudden and hugely dangerous, and have an increasing impact on mine safety and efficient production. [0003] At present, the traditional detection methods of concealed disaster areas mainly include drilling method and geophysical detection. The drilling method is only a "point evaluation" or limited area engineering exploration of the potential area of ​​coal-rock dynamic disaster...

AI Technical Summary

Problems solved by technology

The current passive potential / electromagnetic monitoring results are mainly used in the real-time warning of hidden disasters in mines, but have not been applied to regional risk monitoring and assessment, and the accuracy of time warning and spatial area determination of near-disaster danger needs to be further improved

[0005] In addition, the current gas control and disaster prevention measures such as hydropower lack effective whole-process and full-space detection and evaluation methods
