| 摘 要： | 隧道施工中经常会遇到煤矿采空区,采空区的探测是工程物探领域的疑难问题之一。常规的反射地震方法在地质结构横向变化较大的山区效果不佳,电磁方法对无填充的高阻采空区很不敏感。SSP来源于以地震散射理论为基础的隧道地质超前预报技术TST,与TST不同的是SSP采用地表观测方式,用于煤矿采空区的探测。在复杂地形地质条件下查清了埋深120 m范围内煤层与采空区的分布。这项研究表明地震散射技术可以作为一种新的地震勘探手段。

| Abstract: | The tunnel construction often encounters coal gob area,the exploration of gob is one of the problems in the field of engineering geophysical.Traditional reflection seismic method is ineffective in mountain area which landscape changes dynamically.Electromagnetic method is not sensitive in non-filling high impedance gob.SSP is derived from TST tunnel geological prediction method which bases on seismic scattering theory.Different from TST technology,the SSP technology uses surface observations for the detection of the coal mining area.The distribution of coal seams and range gob area within the depth of 120 m is investigated clearly under complex topographic and geologic conditions.This study indicates that seismic scattering technique is a new seismic exploration technique. |
