横波震源的设计及激发效果
|
摘要
针对横波地震勘探方法是一项有前途、应用范围广的技术,浅层横波勘探的关键问题是震源问题,如何制造出适合野外工作特点的低噪声、大能量、易于操作、经济实用的横波震源是推广横波地震勘探技术的关键;结合横波地震勘探技术在伊敏煤田一露天矿横波地震勘探中的应用,对横波震源的特性进行了分析,对不同特性的横波震源在不同介质中的激发效果进行了试验分析,分析了影响激发效果的因素及采取的各种措施,得出如下结论:在野外采集时,注意提高资料的信噪比和分辨率非常重要,不能只靠数据处理来提高资料的分辨率,另外,要想取得好的激发效果,震源与地表耦合的好坏很重要.
The seismic exploration method with shear waves is a promising and widely used technology.In a shallow transverse wave exploration,its seismic source is a key problem.The key for its wide application is to make a seismic source suitable for field work,such as low noise,high energy,easy in operation,economic and practical.The transverse wave seismic exploration technology has been applied at a surface mine in Yimin coalfield.The characteristics of transverse wave source and the stimulation effect of transverse wave source with different characteristics in different medium were tested and analyzed to understand their influence factors and various measures taken.It concludes that in field data collection,the improvement on signal-to-noise ratio and resolution is very important except the improvement of resolution in data processing.In addition,to obtain a good stimulation effect,the coupling between seismic sources and ground surface is very important.
