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 unfavorable influence brought by fault in coal mining area under complicated geological conditions, two-dimensional seismic method is used to detect the coal seam’s fault structure and fault location in mining area.The results show that using 2D seismic method, The characteristics of the reflected wave are obvious, the waveform is relatively stable, and it can be traced continuously in the survey area, which can better reflect the undulation morphology of the coal measure strata. In the process of data processing, the signal with high signal-to-noise ratio, high fidelity and high resolution Rate as the center, static correction, deconvolution as the focus, according to the trial processing, batch processing, improve the processing of three steps, to maximize the accuracy of the analysis results, effective combination of seismic time profiles and instantaneous phase profile Reflect, more clearly and intuitively to detect the test results, the detection results are more significant.
