Real-time forecasting method and warning system for water disaster in front of excavation roadway

Abstract

The invention discloses a real-time forecasting method and a warning system, wherein an electromagnetic wave field and a temperature field are used for monitoring a water disaster in front of an excavation roadway in a combined mode. The system comprises an explosion-proof main machine 10, an electromagnetic wave emitting coil 1, an electromagnetic wave receiving coil 2 and a thermal infrared temperature sensor probe 4. According to the method, the electromagnetic wave filed and a thermal infrared field are used as signal sources for conducting real-time collection and recording on wave field signals, primary results are obtained after the wave field signals are subject to data processing, a multi-field multi-parameter information fusion judging system is used for conducting fusion, correlation and comprehensive analysis on the processing results of the two kinds of wave field signals, grading and forecasting of water-containing geologic bodies are completed, and according to a set threshold, an intelligent voice alarm conducts alarming on the water-containing geologic bodies reaching the danger level. The real-time forecasting method and the warning system overcome the defect that in the prior art, real-time forecasting cannot be conducted on the water disaster in front of the excavation roadway, fully utilize the advantages of the different physical fields, improve the real-time monitoring and forecasting precision, achieve the purposes of full-process monitoring, and realize real-time forecasting and alarming of the water disaster in front of the excavation roadway.

Description

technical field [0001] The invention relates to a system for real-time monitoring, forecasting and alarming of roadway water hazards in mine engineering and underground engineering, in particular to a method and alarm system for advance real-time forecasting of water damage in front of tunneling roadways by using electromagnetic wave field-temperature field combination. Background technique [0002] The difficulty of advanced real-time forecasting of water damage in front of excavation roadway is that the water damage in front of the roadway cannot be seen or heard. The actual production requires that the distance of early forecast and alarm be as large as possible, and the requirement is to reach 100m. The existing technology can only perform advanced detection of water damage in front of the roadway, but cannot perform advanced real-time monitoring, forecasting and alarming. The technical methods that can be used for advanced detection in mine roadways include seismic meth...

AI Technical Summary

Problems solved by technology

Water-containing caves and water-saturated broken zones in the strata ahead of the roadway are easily detected by ground radar, but the detection distance of ground radar is relatively small, within about 20m, and it is easily affected by the side walls of the roadway and metal facilities, which cannot meet the advanced detection requirements Real-time monitoring and forecasting cannot be performed when the distance reaches the requirement of 100m

[0009] The above-mentioned technologies can only realize advanced detection of water-bearing geological bodies in front of the roadway at present, but cannot realize real-time monitoring and forecasting and early warning. Therefore, advance real-time forecast and alarm of water damage in front of the roadway are very necessary to ensure mine safety
