摘要
针对矿用微震检波器采集的微震监测信号极易受到外界随机干扰的影响,进而直接影响到微震监测数据分析的准确性问题,基于检波器的工作原理、技术参数和性能指标的对比分析,通过新型矿用检波器阵列的结构设计与叠加降噪方法研究,提出了一种提高矿用微震检波器信噪比的方法,实现了检波器信噪比提升达两倍以上,有效解决了传统检波器信噪比低、抗干扰能力不足等问题。
The microseismic monitoring signals collected by the microseismic geophone are highly susceptible to external random disturbance,which directly affects the accuracy of the microseismic monitoring data analysis.Based on the comparison of the working principle,technical parameters and performance indicators of the geophone,and through the research of structural design and superposition noise reduction method of new mine microseismic geophone array,a method for improving the SNR of mine microseismic geophone is proposed,which realizes that the geophone SNR is more than twice and effectively solves the problems of low SNR and poor anti-interference ability of traditional geophone.
