【摘要】 由于半沙漠区地表松散,沙层厚度大等问题,常规二维地震勘探的精度不能达到解释效果。本次采用高密度三维地震勘探技术对陕北侏罗纪煤田榆神矿区小保当井田进行地震勘探,并联合CGG、Promax和绿山等地震资料处理软件对其进行分析,有效地提高了半沙漠地区地质构造的成像精度,为矿井建设提供准确依据。更多还原

【Abstract】 As the questions of loose surface and big thickness in semi- desert area,the precision of the conventional 2D seismic exploration cannot reach the explanation requirements. The paper uses the method of high- density 3D seismic exploration technology in Xiaobaodang coalfield of Yushen mining area. The exploration data is analyzed by CGG,Promax and Green Mountain seismic processing software. The technology improves the imaging accuracy of geological structures in semi- desert area and provides accurate basis for the mine construction.更多还原
