阜新矿震台网子台地动噪声分析

Analysis on the background noise at the sub-stations in Fuxin Mine Seismic Network

通过对辽宁省阜新矿业集团数字矿震监测台网4个子台台址背景噪声进行分析和计算,得出了各子台台址背景噪声功率谱密度曲线、噪声地动速度均方根值(RMS值)、有效测量动态范围。结果表明,各个子台的台址环境和观测仪器的性能良好,背景噪声水平符合中国地震局数字地震观测技术规范要求。

Through the analysis and calculation of background noise for the 4 sub-site of Fuxin Mine Seismic Network in Liaoning Province, we carry out background noise power spectral density curve, the RMS value of the background noise, the effective dynamic range. The results showed that all sub-station sites and observation equipment in good condition, the back-ground noise level in line with digital seismic observation technology specification of China Earthquake Administration.
