摘要

研究目的：在铁路选线地质勘察中，铁矿采空区勘察是一个较新的的课题。在地震与电磁法等常规方法勘察的基础上，针对铁矿的成矿特点与采空特征，应用高精度重磁测量技术对此进行了卓有成效的尝试，并对各种技术方法的优势和互补性进行了探讨，获取了铁矿采空区的物探异常响应特征，形成了一套有效的工作方法。

研究结论：通过邯长铁路涉县铁矿采空区的勘察，以高精度重磁测量为主的综合物探技术取得了较为理想的应用成果。高精度重磁测量、地震映像、瞬变电磁测深及密点距直流电测深等方法，其资料相互对比验证，准确的圈定出采空异常区并划定采空区边界，为采空区评价和铁路选线提供了有力的地质依据。本项目所获得的工作经验，对类似情况的铁路地质勘察具有很强的指导性意义。

Abstract

Research purposes: The geological survey in iron mine goaf is a quite new subject for the geological survey for railway alignment. Based on the Seismic and electromagnetic methods，the hish—precise gravity and magnetic measurement technology wag successfully tried to conduct the geological survey in the iron mine goaf according to the characteristics of metallogeny and iron mine goaf．The discussion wa$made on the advantages and eomplementarities of different methods to seek the characteristics of the abnormal response in iron mine goaf and establish a set of working methods．

Research conclusions: The integrated geophysical exploration technologies of taking high—precise gravity and magnetic measurement as the principal technology WaS used for the geological survey in iron meine goal in She County along the Handan—Changzhi Railway， obtaining a rather perfect result．Through the comparison and verification of the data got by means of high—precise gravity and magnetic measurement，seismic reflection，TEM sounding and tightly point spacing DC sounding metheds，the abnormal area and boundary of the 90af were mapped out，which could provide very useful geological basis for the goaf evaluation and railway alignment．The experience from this project has a great directive significance to the geological survey for railway in the similar situation．
