摘要: 为研究天然源面波勘探方法在固体矿产勘查尤其是在深部找矿中的应用效果,选择小包庄铁矿区已知勘探线进行方法试验。在前期研究的基础上,采用线性排列的方式部署了天然源面波测点,共完成了32个测点、总长度 3 100 m 的数据采集工作; 采用扩展空间自相关法获取了每个测点的频散曲线,并对频散曲线进行反演并通过插值计算,获得了整条剖面的横波速度结构; 根据地质和钻孔资料,划分了岩性层和断裂。通过与已知资料对比分析,认为该方法取得了较好的勘查效果,表明天然源面波勘探方法在深部找矿中具有较好的应用前景,该区深部具有较大的找矿潜力。Abstract: In order to study the application effect of the natural-source surface wave exploration method in solid mineral exploration, especially in deep mineral exploration, the authors in this paper carried out study on the known exploration line of Xiaobaozhuang iron mine. The natural-source surface wave survey points were deployed in the linear way based on previous research, and a total of 32 survey points with a total length of 3 100 m were completed. The extended space autocorrelation method was used to obtain the dispersion curve of each measurement point, and shear wave velocity structure of the whole section was obtained by the inversion of dispersion curve and interpolation calculation. The stratigraphic structure and faults were divided according to the geological and borehole data. These exploration results were proven to be good, compared with the known data, indicating that the natural-source surface wave exploration method has a good application prospect, and the deep part of the study area has great prospecting potential.
