频谱分解技术在探测煤矿巷道中的应用

The Application of Spectrum Decomposition Technique in the Detection of Coal Mine Tunnel

就沁水盆地某矿的高分辨率三维地震数据中的巷道异常现象,运用频谱分解方法进行了精细解释。研究结果表明:利用该技术可以查明埋深大于460m、巷高2.6m的双层煤岩巷,异常特征反映明显,边界清晰,解释成果与实际掘进巷道资料吻合较好。

In the light of some unusual phenomena of tunnel in HR 3D seismic data of a certain mine in the Qinshui Basin,this paper makes the detailed interpretation with spectrum decomposition technique,and based on the research results,points out that spectrum decomposition technique can be used to find out two-layer coal rock tunnel with the burial depth of more than 460 m and height of 2.6 m,the unusual characteristics reflect obviously,the boundaries are clear and the interpretation achievements fit well the actual tunneling data.
