甘肃祁连山大容量气枪主动源最大探测范围
Maximum Detective Range of the Large-volume Airgun Active Source in Qilian Mountains,Gansu Province
摘要
Abstract
Numerous waveform data,which continuously vary owing to excitation by the large-volume, airgun active source in Qilian Mountains,Gansu Province and are recorded by the Gansu and Qinghai digital seismic network,are stacked in this study.The results reveal that after single excitation,the air-gun source signals could be detected by the GLT station located 304 km away from the source;the sig-nals stacked 110 times could be detected by the AXX station located 412 km away from the source;and the signals stacked 4,600 times could be detected by the WTM station located 677 km away from the source.The findings of this study are of great scientific importance for improving the monitoring capabili-ty of the large-volume,airgun active source observation system in Qilian Mountains,extracting weak signals,and discussing the velocity change of internal medium in Qilian Mountains.关键词
