摘　　要：以表浅层为沙丘的神府煤田和厚黄土丘陵地表的河东煤田煤矿采空区三维地震资料解释为例,在分析煤矿采空区岩层形变机理及地质特征的基础上,利用常规三维地震时间剖面解释和顺层属性解释相结合的方法,总结了煤矿采空区三维地震资料反射波特征及地震属性在采空区解释方面的特点。通过实例研究表明,以目前地震地质解释精度能够圈定复杂地震地质条件区的煤矿采空区范围。Based on the 3D seismic survey data interpretation on the mine gobs in Shengfu coalfield with shallow strata of dune and Hedong coalfield with thick loess hills surface,through analyzing the strata deformation principle and geology features in the coal gob area,the paper ap-plies the normal 3D seismic prospecting method combining time profile interpretation with bed-ding property interpretation,and sums up the characters of 3D seismic reflective waves and seis-mic attributes in coal mine gob area？？ The research results of the two cases indicate that the pres-ent interpretation precision on seismic geology is enough to provide reliable information for coal gob area scope locating in complex seismic geology area.
