摘　　要：结合采空区特点,依据地震绕射理论及次生震源知识,采用地震映像技术进行研究,通过单点激发、单点接收、偏移距保持不变沿测线逐一测量方式,通过侧线反射时间剖面资料分析,确定采空区空间分布及形态特征。从原理到实际勘察进行阐述,实现以地震映像技术探测采空区。Combining with the characteristics of mined-out area, on the basis of seismic diffraction theory and seismic secondary source knowledge, it use seismic imaging technology to study, by the single point, single point receiving, offset remains the same way along the line one by one, measuring way, through the analysis of lateral line reflection time section data, to determine the spatial distribution of mined-out area and morphological characteristics. This paper elaborates the principle to the actual investigation, so as to achieve the goal of seismic imaging technology detecting goaf.
