在白银市魏家地煤矿,为了查明F1-2断层组走向及其推覆体构造下煤层起伏形态及构造分布情况,进行了三维地震勘探.针对该区复杂的地震地质条件,在资料采集以及处理时均采用了相应的技术措施,获得了品质较高的三维数据体；在资料解释过程中采用常规地震资料解释辅以地震属性解释相结合的手段,解释的推覆体逆掩构造下的地质构造特点比较明显,圈定了断层煤的分布范围.%In order to find out the strike of Fl-2 fault set and the coal seam undulation morphology as well as the structure distribution under its nappe structure in the Weijiadi coal mine of Baiyin City, the author conducted three-dimensional seismic exploration. Taking into account the complex seismic geological conditions of the study area, the author adopted corresponding technical measures for data acquisition and processing and obtained high-quality three-dimensional data. In the process of data interpretation, the means of adopting seismic data interpretation assisted by seismic attribute interpretation was employed. As a result, the interpreted geological and structural characteristics under the nappe overthrust structure are fairly obvious, and the distribution range of the fault coal is delineated.
