摘要
为了提高矿井地震的探测效果,基于矿井地震勘探原理,结合国内外现有矿井地震检波器使用情况,以赵固一矿井下地震探测为工程试验,采用理论分析、现场实测等方式,确定矿井地震检波器的不同安装方式对采集信号的影响。研究表明:矿井地震检波器的安装方式会直接影响地震信号的采集质量,在常用的孔内安装、锚索安装、钢钎安装3种方式中,采集信号质量呈“孔中安装>锚杆安装>钢钎安装”趋势,孔中安装方式的检波器采集信号更加清晰、稳定。
In order to improve the detection effect of mine seismic,based on the principle of mine seismic exploration,combined with the use of mine seismic geophone at home and abroad,taking underground seismic detection in Zhaogu No.1 mine as engineering test,the influence of different installation modes of mine seismic geophone on signal acquisition is determined by means of theoretical analysis and field measurement.The results show that the installation method of mine seismic geophone will directly affect the quality of seismic signal acquisition.In the commonly used hole installation,anchor cable installation and cone rod installation,the quality of the collected signal is“hole installation>anchor cable installation>cone rod installation”trend.The signal collected by the seismic geophone installed in the hole is more clear and stable.
