Seismic Signal Identification, Location And In Mine Safety Management Application

Micro seismic are mine in mining process and induced mining strata structure rupture suddenly instability and failure of a dynamic phenomenon, it is the influence of safe production in mines is very important one of natural disasters. If the micro earthquake if it happens, could affect the normal production, and cause certain persons and property losses. Through the mining experience, can know, with mining the passage of time, the majority of mine into deep mining condition, such micro earthquake probabilities and severity will greatly increase, the causes of casualties and property losses will further increase. Through analyzing the characteristics of micro earthquake occurred, and conditions lead to its occurrence of some influential factors were machine rational analysis of possible micro of a seismic event for empirical place and time for discussion and analysis the positioning precision micro focal optimize summarized and discussed, suitable for tin tieshan pb-zn mine earthquake monitoring and analysis system microprocessor, this is later establish intelligence, automation and network of earthquake monitoring and analysis system of micro do plenty of theory and practice of preparation.Combining with independent intellectual property rights of the tin tieshan lead-zinc mine earthquake monitoring and analysis system, micro research its sensor placement rules, acquisition card selection, collecting frequency set range and related parameters optimization and selection. For the jamming system operation of electric power, rtificial natural factors, taken from inside to outside comprehensive measures to solve these problems, the actual operation shows that, in these protective measures, under the protection of the this system can normal good run, and achieved forecast good effect.This article mainly introduced the tin tieshan lead-zinc mine earthquake monitoring and analysis system of micro construction, implementing and on-site monitoring results, and gives the corresponding function and interface are introduced. Given monitoring to micro seismic signals and jamming signal, through HHT theory to its collection of micro seismic signal de-noising, through the automatic loot P wave arrives, thus making preparation for source orientation.This paper studies the applicable to mountain lead-zinc deposit solder iron characteristics of micro earthquake source localization algorithm, first by have automatic loot P waves arrives, then use source scanning algorithm for its positioning, then with actual monitoring of micro earthquake location, comparing its absolute error less than 8.1 m, can fully satisfy the normal production technology needs.Finally, according to the tin tieshan lead-zinc mine earthquake monitoring and analysis system of micro long-term monitoring data obtained are analyzed and summarized, was proposed for tin tieshan lead-zinc deposit based on dynamic monitoring of the strata stability advanced prediction method, through this method for two months after possible micro earthquake place and time for advanced prediction, the forecast, compared with the actual situation, the error is within acceptable limits. This also is later mine micro earthquake monitoring and analysis provides a very worthy of learning ideas and the basis.
