摘要： 近年来，随着国家对煤矿整合、兼并力度的不断加大，煤矿采空区的探测越来越受到人们的重视。由于采空区本身地球物理条件的局限性，使其作为地震盲区历来被三维地震勘探所回避。随着三维地震勘探技术在煤田上的蓬勃发展，使得采空区的探测成为可能。结合山西王家岭煤矿首采区三维地震勘探的实例，分析了采空区地震剖面的地震响应特征以及地震属性在采空区上的变化特征，认为煤矿采空区在时间剖面上的地球物理特征以及地震属性特征均比较明显，因此，三维地震探测采空区是可行的。

Abstract: With the increasing of integration, mergers and acquisitions of the coal mines in China, the survey of the goaf is paid more and more attention to in recent years. The limitations of geophysical conditions of the goaf make it always avoided by 3D seismic exploration as the blind area. However, the development of 3D seismic exploration of coal fields allows the goaf survey or detection to become possible.Taking the 3D seismic exploration of the panel of the Wangjialing coal mine in Shanxi as an example, this paper analyzed the seismic response characteristics of the goaf seismic profile and the characteristics of changes of seismic attributes in it, and showed that the characteristics of both seismic profile and seismic attribute on the coal goaf are all obvious, hence the coal goaf survey by 3D seismic prospecting is feasible
