摘要
利用河南新密超化镇某矿区布设的密集临时地震台网观测资料,通过微震震源精确定位手段,实现强干扰背景下该地区某煤矿地下开采面的定位追踪试验研究。微震定位后,爆破点位置的水平精度为±70m,垂直精度为±500m。试验研究结果表明,利用高密度数字地震台网资料,可较为准确地监测矿山地下开采面的动态变化,从而实现对矿产资源越界开采和小矿非法开采的有效制约和监督。同时,本次试验结果显示地震台网的监测控制范围受爆炸源能量、地下开采面的深度、监测区背景噪声、监测仪器的灵敏度和抗干扰能力等因素影响,试验结果可对今后矿区地震监测台网的合理布设提供有效指导。
The purpose of this study was to use micro-seismic source location to locate,track,and observe the underground coal mining surface(shot point)near one coal mine in Xinmi city,Chaohua county,Henan province.Following the micro-seismic location,the horizontal precision of the shot point was 70 m while the vertical precision was500 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 restriction 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,instrument 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.
