地下煤层自燃区地震勘探研究
Study on Seismic Prospecting for Underground Coal Measures Self-ignite Area
【摘要】 本文旨在探索黄土塬地下煤层自燃区地震勘探技术。研究表明,火烧区在折射层析成像速度剖面、散射波地震记录、共偏移距地震剖面、地震反射波时间剖面中均有表征显示,而有别于采空区的波场特征。
【Abstract】 Seismic prospecting technique for coal burned area in the loess plateau is discussed in this paper.There are distinct wave characteristics about coal burned area,different from wave characteristics about mined-out area,in the refraction velocity section,the diffraction record,the common offset section and the reflection section.
