The Signal Identification And Localization Of Rockburst And Their Application At Muchengjian Colliery

Rockburst is earthquake activity that aroused by exploiting the surface , shallow (several hundreds of meters) and deep mine (kilometers of the following) , which is one of the significant disaster being to affect the safety in the mineral production. As time goes by, a lot of coal mine exploits entrance deep mine , the rockburst will also be getting serious with every passing day , therefore it is essential to study rockburst in order to loss cutting down a disaster. Despite the rockburst had being analysed for hundreds of years, but the aspect fixing position but in studies of localization and the phase automation identification is few.With the study of the occurrence mechanism, classification to rockburst, and the seismic wave spreads law. It made theory preparation for Mu Chengjian rockburst monitoring and orientation system.This paper have introduced the segment, the monitoring program and localizing host program of Mu Chengjian rockburst monitoring and orientation system, have compiled the interface fetching data automatically. It is a basis of signal identifying and localization. The localization theorem of single station, two stations, three stations and many stations were studied.By expounding to the signals of rockburst and their disturbance factor, linking up with the received data by Mu Chengjian Colliery. Writer had carried out a automatic preparation of rockburst signal by VB procedure using a signal-to-noise ratio. The paper has introduced earthquake signal real time identification, and sumed up out two kinds method of P wave arrival time voluntarily: standard deviation law and auto-regression law.Combining with Mu Chengjian rockburst monitoring and orientation system, method of fetching arrival time automatically was applied to the signal. At the same time, the method of localization also have been tested, which reaching these method was not bad apply to actual, but contained existence error. Have brought forward suggestion to the software of data processing system and have looked into the distance finally.
