密集台网微震定位技术在矿山开采动态监测中的应用研究
Application of the Dense Network Micro-seismic Location Method to Dynamic Mining Monitoring
摘要
Abstract
The purpose of this study was to use micro-seismic source location to locate,track,and observe the under-ground coal mining surface (shot point)near one coal mine in Xinmi city,Chaohua county,Henan province.Follow-ing the micro-seismic location,the horizontal precision of the shot point was 70 m while the vertical precision was 500 m.The experimental results showed that we could accurately monitor dynamic changes of the underground coal mining surface through high-density digital seismic network materials.This technique contributes to the effective re-striction and supervision of the cross-border exploitation of mineral resources and illegal exploitation of small coal mines.Results of the study also showed that the scope of monitoring was affected by a number of elements,such as energy exploration,depth of the underground coal mining surface,background noise in the monitoring area,instru-ment sensitivity,and anti-disturbance.The results provide reasonable guides for an optimized layout of the seismic network in the mining area.In the use of seismic networks,microseism localization has made certain progress and the resulting error in localization is controllable.Increases in the pointing accuracy will make it possible for this technique to have the practical application in the mining area.关键词
