Description

[0001] technical field [0002] The invention relates to the technical field of mining microseismic detection equipment, in particular to an automatic labeling system for microseismic waveforms. Background technique [0003] Rock burst is one of the coal-rock dynamic disaster phenomena that seriously threaten mine safety production. Rock burst has occurred in major mining countries in the world such as Germany, South Africa, the former Soviet Union, the United States, Poland, Japan and my country; Its sudden, sharp and violent damage characteristics have a serious impact on the normal production of coal mines, metal mines, tunnels, etc., and cause huge economic losses and casualties. As the mining depth of underground mines increases, the risk of rock burst is also gradually increasing; the characteristics of rock burst in coal mines are: 1) suddenness, mainly manifested in the absence of obvious signs before the occurrence of rock burst; 2) instantaneous 3) Destructive, man...

AI Technical Summary

Problems solved by technology

[0004] In coal mining activities or when there are rock formation failure events such as cracks, the instantaneous rupture of the rock mass will excite elastic waves. These elastic waves carry the information of the source and propagate to the surroundings relying on the elastic medium of the rock mass. If a device or system can be developed , use vibration sensors to measure these elastic wave signals at a distance, and determine the occurrence time, spatial position, scale, intensity and nature of the rupture according to the characteristics of the monitored microseismic signals, then the prevention and monitoring of rock burst can be realized. However, not only is there a lack of such a monitoring system in the prior art, but a more important step in the monitoring process is to mark the microseismic elastic wave waveform, that is, to mark the moment when the microseismic occurs. In the prior art, the method of manually moving the scale is usually used Labeling is not only less efficient, but also less accurate
