摘　　要：近年来,煤窑采空区塌陷发生频繁,严重威胁着铁路工程建设和人类生命财产的安全,如何查清采空区的埋深、位置及空间延伸范围,对于指导煤窑采空区的整治尤为重要。笔者首先简要说明了地震CT层析成像的基本原理,然后结合工程实例,探讨了层析成像的应用效果。The frequent collapse incidents of coalfield mined-out areas in recent years have severely threatened the safety and security of life and property, as well as those of railway construction. As a result, it is of great significance to search out the buried depth,location and spatial extension scope of coalfield mined-out areas for better instructions and management. This paper intends to briefly explain the principles of seismic computerized tomography in the fillet place,then discuss the applied effects of seismic tomography in combination with railway construction cases.
