Description
Technical Field
The invention belongs to the field of mine safety, and particularly relates to a roadway rock burst risk monitoring method and device.
Background
At present, the technology for preventing the rock burst risk is mainly studied in the field of acoustics. Specifically, in the acoustic field, three directions are divided: microseismic technology, acoustic emission technology, and acoustic detection technology. The microseismic technology is better understood, and mainly comprises the steps of inserting a plurality of sensors into surrounding rock and monitoring the tiny vibration in the surrounding rock. When the surrounding rock mass is deformed due to elasticity, the rock mass will generate a relatively small mechanical shock. Such vibrations can be monitored by a microseismic sensor. The mode of various vibrations is accumulated and distinguished, so that a micro-vibration technology is formed, and of course, when a rock mass generates micro vibrations due to elastic deformation, various sound waves are generated in the rock mass due to various friction, generation of micro cracks, and the like. By monitoring the sound wave, the vibration and microcrack generation conditions of surrounding rock can be obtained, and the accumulation and development conditions of rock burst risks can be obtained, which is an acoustic emission technology. Macroscopic, elastic deformation energy of rock mass is accumulated to a certain extent, scattered small-scale small rock ejection is generated, and the small rock ejection is influenced by rock mass and elastic deformation energy and accompanied by different sounds, and conversely, the judgment of rock burst risk can be obtained through the accompanied sound of the small rock ejection, and the method is an audio detection technology.
The three methods can predict the rock burst risk to a certain extent. However, they all have a relatively difficult problem to solve: the problem of influence of environmental factors in actual roadways is illustrated by taking a microseismic technology as an example. In a laboratory environment, the microseismic technology can well forecast rock burst, but in an actual roadway, the microseismic technology is frequently misreported, mainly because various interference factors are too many and complex in the actual environment, and the current system does not reach the level of intelligent judgment yet.
Because of the thermoelastic effect of the object, the roadway rock mass can generate and release heat energy under the condition of bearing external force, and the existing research finds that: rock infrared radiation temperature, infrared spectrum radiation intensity and infrared thermal image change along with rock stress; in the loading process of the rock, the infrared radiation intensity of the surface of the rock presents a characteristic of stepwise change along with the development of stress; the characteristic roughness of the infrared temperature field can be in a 'decline-rise' trend in time sequence, and the characteristic can be used as a specific precursor of the infrared radiation temperature field before rock burst occurs, so that the infrared temperature field has a certain reference significance for roadway rock burst early warning.
