摘　　要：煤矿生产中对于煤层分岔间距要求精度较高,传统地震定性解释煤层分岔的精度不能满足煤矿生产要求。文章在正演分析的煤层分岔识别对地震数据主频要求的基础上,提出利用谱蓝化技术对地震资料进行拓频处理,然后对谱蓝化后的地震数据利用地震波形分类解释技术进行煤层分岔间距识别的处理解释一体化组合方法。通过对山西某矿区13号煤层分岔现象进行识别,实际应用表明,该技术方案可有效提高地震资料的分辨能力,大幅提高煤层分岔现象的识别能力与精度。Since coal mine production requires high precision for coal seam bifurcation spacing,the traditional seismic qualitative interpretation can not meet the requirements.Based on forward analysis of coal seam bifurcation identification requirements for seismic data frequency,an integrated method for processing and interpretation is proposed:firstly,the spectral bluing technology are used in the extended frequency processing on seismic data;then,based on the seismic data,the seismic waveform classification and interpretation technology is used to identify the coal seam bifurcation spacing.The application in No.13 coal seam in a mine in Shanxi shows that this technology can effectively improve the resolving power of seismic data and greatly improve the identification accuracy of the coal seam bifurcation.
