摘要

为排除安全隐患,对山西省某煤矿周边的小煤窑采空区进行探测。在资料处理中,通过对比性研究,发现采空区的时间剖面会出现,反射波同相轴下凹时间发生延迟、反射波同相轴中断、不连续或间断连续等现象。利用地震时间剖面反射波的特征对采空区进行解释,查出了勘探区内3号煤层采空区7处,,共计面积约0.808 km2,其中3个采空区现已揭露,采空区的解释范围和所揭露的基本相符,解释成果得到很好验证。
At present,coal resources in Shanxi Province are being reformed,and the resource reserves will be checked after the merging of small coal pits.It is necessary to investigate the structure of the goaf that threats mine production,so as to get rid of hidden danger.Through a comparative study during data processing,the author has discovered that reflection seismic wave phase axis is concave downward,interrupted,and discontinued or interruptedly-continuous in the seismic section if the goaf is buried.In this paper,the goaf is interpreted by using seismic time section reflection wave feature.The result of seismic exploration for the goaf is as follows: totally seven 3#-coal goaf areas have been discovered,the total goaf area is 0.808 km2,and the limits of three goaf areas agree with the drilling data,which means that the interpretation result is well verified by drilling data.
