Description

technical field [0001] The invention relates to a technique and a device for real-time monitoring of coal rock concrete deformation and cracking process or prediction and forecasting of coal rock concrete dynamic disasters through continuous and uninterrupted monitoring of coal rock concrete deformation and cracking electromagnetic radiation (EME) information. The invention belongs to the technical field of mine safety monitoring and forecasting equipment. Background technique [0002] The range of coal-rock dynamic disasters is very wide, involving many engineering fields and natural disasters. Under mine conditions, there are coal and gas outbursts, rock and gas outbursts, mine rock burst, roof subsidence, and slope slips, etc.; on the ground, there are mountain slips, earthquakes, dam foundation instability, and rock-concrete building instability. collapse etc. The hazards of coal-rock dynamic disasters are enormous, not only bringing a larg...

AI Technical Summary

Problems solved by technology

Invention patent "Method and device for predicting gas-bearing coal and rock concrete disaster" (ZL98111185.8) through non-contact monitoring of the electromagnetic radiation signal generated when the loaded coal rock mass deforms and ruptures and its short-term (several minutes) change law, the coal mine can be predicted. The danger of coal-rock dynamic disasters such as gas outburst and rock burst reflects the instantaneous state of a certain stage in the evolution process of coal-rock dynamic disasters. It has not realized continuous and uninterrupted monitoring and forecasting, and cannot share the KJ coal mine. Resources for Safety Monitoring Systems

[0009] The utility model patent "Electromagnetic Radiation Monitoring Device for Coal and Rock Dynamic Disasters" (Patent No. ZL 01 272808.X) can perform continuous monitoring with an external power supply, but it cannot be connected with the KJ series coal mine safety monitoring system and cannot share the safety monitoring system separate power supply and transmission channel, separate wiring and separate power supply are required to realize remote monitoring, and the forecasting function is weak

[0010] There are no mature technologies and devices for real-time monitoring and forecasting of small-scale coal-rock concrete disasters (such as coal and gas outbursts, dam foundation instability, landslides and rock bursts, etc.) by using electromagnetic radiation methods and their hazards.
