【摘要】 针对山西原平盘道煤矿勘探区地形条件复杂、煤层埋深浅、部分地区黄土覆盖、部分地区基岩出露等三维地震勘探不利因素多的特点,采用了小炮距、小道距、高覆盖次数宽频带接收的三维观测系统,数据处理时采用地表一致性振幅补偿、初至折射静校正等手段最大限度提高资料分辨率。通过本次勘探进一步查明了测区内主要可采煤层的赋存形态和深度,共解释断层31条,未发现地质异常体。

【Abstract】 based on the numerous three-dimensional seismic prospecting adverse factors such as swallow burial depth of coal seam,complex terrain conditions,thick loess and exposed bedrock covered in some area,local obstacles in YuanPing Pandao coal mine exploration in Shanxi province,this article used the methods of small shot point spacing,receive point distance,high coverage frequency wideband received conventional 3D observation system and selecting the best stimulation and receiving position special 3D observation system of technology.data processing in first arrival refraction wave statics,compensation and surface consistent correction of amplitude,and other means to maximize the data resolution and shallow reflection wave loss problem.Through this exploration,we further find out the measuring the main minable seam occurrence form and depth,a total of 31 explain fault,and find no geologic abnormal bodies.
