摘　　要：采空区在煤矿生产和地面施工勘探中危害严重.在煤矿生产和施工前探测采空区,圈定出采空区的范围,已成为当前三维地震的一项十分总要的研究课题.本文分析了采空区形成的原因,划分了不同的采空区类型.通过应用Tesseral-2D全波场地震模拟软件包对采空区进行正演模拟,建立不同类型采空区的地质模型,在这些地质模型上模拟激发,对所得到的时间剖面的地震特征进行分析.As everyone knows that the damage of gob area is serious in coal mine production and construction of ground.Detecting the gob area before the production and construction of the coal mine and Marking out the scope of the mined-out area has become an important research topic in the 3D seismic exploration.This paper analyzed the formation mechanism of the mined-out area and Divided the different kinds of mined-out area.The Seismic full-wave field modeling software Tesseral-2D was introduced into the forward modeling to the Seismic response of the goaf.This paper Set up geological model of different types of mined-out area, Stimulated on these geological models and analysed the characteristics of Seismic section.
