摘　　要：为了解决复杂地质条件下煤矿采区断层给开采带来的不利影响问题.采用二维地震法,对矿区煤层断层构造及断层位置进行探测.结果表明:应用二维地震法对探测的矿区获得的反射波变化特征明显,波形比较稳定,在测区内可连续追踪,能较好地反映出煤系地层的起伏形态;在数据处理过程中,始终以高信噪比、高保真度、高分辨率为中心,以静校正、反褶积为重点,按照试处理、批处理、改善处理三步进行,能最大限度地提高分析结果的精准度,有效结合地震时间剖面图和瞬时相位剖面图的反映,更加清晰直观地观测出探测结果,探测成果较为显著.In order to solve the problem of negative effects under complicated geological conditions of coal mine mining that brings to the fault, using two-dimensional seismic method, the coal seam fault structure and fault location is detected. The results show that the change of reflected wave in the detection of the mine is obvious with the application of two-dimensional seismic method, and waveform is relatively stable. Continuous tracking in the area of the measurement can better reflect the undulating form of coal formation; In data processing, always with high SNR, high fidelity and high resolution as the center, and the static correction, deconvolution is the focus, in accordance with the treatment, batch processing, improve processing three steps, it can maximize the accuracy of the results of the analysis, combining reflect seismic time profiles and cross-sectional view of the instantaneous phase, it can more clear and intuitive observation results, the detection results were significant. It can provide certain technical support and guidance for the future mining area coal seam mining.
