【摘要】 在煤田地震勘探中，当第四系地层厚度较薄时，从野外观测到资料处理都较难得到来自第四系地层底界的反射波，因此无法解释第四系地层厚度问题，而这一问题又常常是要解决的地质任务之一。并且第四系地层厚度的变化也直接影响了深层反射波的叠加效果和构造形态。就此，文章介绍一种初至折射波静校正方法──旅行时分解法，及其在资料处理与解释中的应用。更多还原

【Abstract】 Seismic prospecting in the area of thin Quaternary strata difficuult to get the reflected wave from bottom of Quaternary strata, so can not to interpret the thickness of Quaternare strata. But there are close relationbetween the thickness change of Quaternary strata with stacking effect of deep reflected wave and the structuralform.The method of first arrival refraction wave statics, travel-time decomposition, may be contributed to resolve above - mentioned problem.更多还原
