【摘要】：高性能槽波地震勘探仪器的研制能够有力推进槽波地震勘探方法在煤矿地质构造勘察等领域的有效应用。通过分析槽波地震勘探实例,对比国内外多款新型槽波地震仪采集站,结果表明:无线遥测式地震仪是槽波地震勘探仪器的主要发展方向;新型采集站都使用有Δ-Σ技术的24位AD转换器,前置增益都是多倍率。地震仪器采集站的性能满足槽波地震勘探需要,但是地震检波器的性能制约了槽波地震仪整机性能的提高。分析6种不同类型地震检波器的原理和性能,目前地震检波器主要是围绕提高灵敏度,拓宽频率响应范围和增强抗干扰能力3个方面进行研究。其中高性能压电式地震检波器在槽波地震勘探中有较好应用前景,进一步介绍了一种压电地震检波器芯体及测试结果。
[Abstract]:The development of high performance groove-wave seismic exploration instrument can promote the effective application of groove-wave seismic exploration method in coal mine geological structure survey and other fields. By analyzing the seismic exploration examples of slot wave, the author compares many new acquisition stations of slot wave seismograph at home and abroad. The results show that wireless telemetry seismograph is the main developing direction of slot wave seismic exploration instrument; The 24 bit AD converter with 螖-危 technology is used in the new acquisition stations, and the pregain is multifold. The performance of seismic instrument acquisition station meets the needs of slot wave seismic exploration, but the performance of seismic geophone restricts the improvement of the performance of slot wave seismograph. The principle and performance of six different types of geophone are analyzed. At present, the geophone is mainly focused on improving sensitivity, broadening the range of frequency response and enhancing the ability of anti-jamming. The piezoelectric geophone with high performance has a good application prospect in groove-wave seismic exploration. A piezoelectric geophone core and its test results are further introduced in this paper.
