摘要
大隆井田位于铁法煤田的中西部,该井田主要可采煤层为侏罗系上部的4、7煤层。根据煤层冲刷带及采空区在地震时间剖面的响应特征(地震波同相轴中断或变弱)以及沿煤层震幅切片变弱的特点,结合其它解释技术,解释该井田南部存在煤层采空区,206孔西部4煤层存在煤层冲刷带。
The Dalong minefield is located at mid-western Tiefa coalfield,workable coal seams are Nos.4 and 7 in upper Jurassic System.According to coal seam scouring and gob area response characteristics on seismic time sections(seismic wave lineup interrupts or attenuations) and amplitude slice attenuating along coal seams combined with other interpretation techniques interpreted gob area and No.4 coal seam scouring to the west of No.206 borehole in the southern minefield
